General Specifications Power - 250 VA to 10 KVA (500 VA to 20 KVA possible if used as auto-transformer) Dielectric Strength - 2500VRMS Hipot Primaries - Dual/tapped primaries: Parallel connected (104V, 110V, 120V - 50-500 Hz) Series connected (208V, 220V, 230V, 240V - 50-500 Hz) Secondaries - Dual/tapped secondaries: DU Series Parallel connected (104V, 110V, 120V - 50-500 Hz) Series connected (208V, 220V, 230V, 240V - 50-500 Hz) Electrostatic Shield - 2 mil thick copper foil connected to ground. The connection may be opened if an ungrounded shield is desired. Terminals - Plated brass screw type terminals Insulation - Class A insulation (105C) As shown on the schematic diagram the "DU" line is designed with dual primaries and secondaries. All four windings are identically rated at 0/104/110/120 volts. This permits series or parallel connections on either primary or secondary. Therefore, a nominal 110 to 110 volt, 220 to 220 volt,110 to 220 volt, or 220 to 110 volt transformer can be set up. The winding taps permit intermediate series ratings such as 208, 214, or 230 volts. It is also possible to make auto-transformer connections by connecting a primary group in series with a secondary group. Such nominal ratings as 440 to 220 volts or 220 to 440 volts can be set up, in addition to the standard ratings described above. A further advantage to auto-transformer connection is the fact that the KVA rating of a particular type is doubled. Series Secondaries Max. Volts Amps Parallel Secondaries Max.

A number of basic assumptions are made to avoid an academic discussion of unnecessary material. For those interested in a rigorous theoretical analysis, there are a number of fine references available. Additionally, circuit analysis using appropriate analysis software (SPICE or its equivalent) is recommended in the rare circumstances where a better understanding of a particular situation is needed, or when it becomes necessary to optimize some aspect of the design. Computer analysis is particularly useful in understanding areas that are difficult to approach using traditional circuit analysis methods, areas such as capacitor RMS ripple current. One of the more esoteric problems encountered by the circuit designer is the selection of power transformer ratings for a particular DC power supply. The designer is immediately confronted with a number of rectifier circuits and filter configurations. For the sake of simplicity, we will make some assumptions which should be valid for 99% of the average designer's applications and present some useful rules of thumb appropriate for conservative design. Filters We will immediately discard the consideration of choke input filters and confine our choice to capacitor input filters because of the following: 1. It is desirable to eliminate the weight and cost of chokes. 2. It can be assumed that if a regulator is used it will provide sufficient extra ripple reduction so that an L-C section is not required. In addition, the regulator will compensate for the poor output voltage regulation with load, inherent in capacitor input systems. The remaining disadvantages of the capacitive input filter system are caused by the discontinuous secondary current flow (high peak-to-average ratio of forward diode current). Current is drawn in short, high amplitude pulses to replace the charge of the filter capacitor which discharges into the load during diode off time. This results in higher effective RMS values of transformer secondary current. However, the transformer average VA rating is the same as the choke input filter because the higher DC output voltage obtained at the capacitor compensates for this effect. In addition, except perhaps for supplies handling very high currents, average semiconductor diodes will meet most of the peak or surge current requirements of capacitive filters. 4. Dual Complementary Supply -- "Full-Wave Center-Tap" (four diodes) The only advantages of the half-wave rectifier are its simplicity and the savings in cost of one diode. Its disadvantages are many: 1. Extremely high current spikes are drawn during the capacitor charging interval (only one current surge per cycle). This current is limited only by the effective transformer and rectifier series impedance, but it must not be too high or it will result in rectifier damage. This short once-per-cycle current spike also results in very high secondary RMS currents. 2. The unidirectional DC current in the transformer secondary biases the transformer core with a component of DC flux density. As a result, more "iron" is needed to avoid core saturation. About the only time it would pay to consider using the half-wave rectifier is for very low DC power levels of about 1 2 watt or less. At these levels a power transformer cannot be reduced very much in size (at reasonable cost) and a small filter capacitor will be large enough for adequate DC smoothing. The remaining single-phase rectifier circuits are of the "full-wave" type. Secondary current surges occur twice per cycle so that they are of smaller magnitude and the fundamental ripple frequency is double the supply frequency (i.e., 120 Hz rather than the 60 Hz of a half-wave system). All full-wave rectifiers also have the same basic rectified waveform applied to the filter capacitor. Other Factors * Full-Wave Center-Tap Uses 12 of secondary winding at a time Requires center-tap Uses 2 diodes * Full-Wave Bridge Uses full secondary winding continuously No center-tap required Uses 4 diodes As can be seen above, the choice between FWCT and Bridge configurations is a tradeoff. The bridge rectifier has the best transformer utilization but requires the use of 4 diodes. The extra diodes result in twice the diode voltage drop of a FWCT circuit so that the FWCT is usually preferable in low voltage supplies. Rectifier Circuit The remaining choice is that of a rectifier circuit configuration. The most common single phase circuits are: 1. Half-Wave (single diode) 2. Full-Wave Center-Tapped (two diodes) 3. Full-Wave Bridge (four diodes) 35 How to specify power transformer & filter ratings The "dual complementary rectifier circuit" is the combination of two FWCT circuits and is a very efficient way of obtaining two identical outputs of reversed polarity sharing a common ground. It is also called a "centertapped bridge rectifier." The diagram below represents a full-wave center-tapped rectifier using a capacitive filter and is the most common selection for moderate power, regulated DC supplies. The following assumptions can safely be made: 1. VREG is approximately 3 volts DC or greater. 2. VRECT is about 1.25 volts DC. 3. VRIPPLE is about 10% VDC peak. The following formula may be used for determining the transformer secondary voltage: Required RMS Secondary Current Rating 0.7 x DC Current Rectifier Type Filter Type* Full-Wave Center-Tap Choke Input Full-Wave Center-Tap Capacitor Input 1.2 x DC Current Full-Wave Bridge Choke Input DC Current Full-Wave Bridge Capacitor Input 1.8 x DC Current *Even though we have dropped choke input filters from this discussion, they are included for reference. For instance, in our particular example (5 V, 2A DC supply) the transformer RMS current would be: for FWCT 1.2 x 2 = 2.4 A for bridge 1.8 x 2 = 3.6 A The total transformer specification would then be: Circuit Secondary Rating Possible "Signal" Parts FWCT 18.5 CT @ 2.4A RMS = 43.2 VA 241-7-20, 36-1 bridge 10.5 @ 3.6A RMS = 36 VA ST-7-10, 241-6 or 7-10, 10-4 Dual Complementary Supply One more common example will be given, i.e., a dual complementary supply for 15 V @ 100 mA DC. VOUT = 15 VRECT = 1.25 VREG = 3 VRIPPLE = 0.75 (1.5 V p-p) VAC = (15 + 3 + 1.25 + 0.75) x 115 x 1 = 19V 0.9 95 M2 1AC = 1.8 x 100 mA = 180 mA RMS The transformer secondary rating is 38 V CT @ 180 mA RMS. Possible Signal parts would be ST-4-36, PC-34-300, PC-40-250. A precautionary calculation remains to be made. That is, the increase in voltage at the filter capacitor (into the regulator) caused by a high line condition. If we assume our highest line voltage to be 130 V AC then the transformer output (compared to low line) would rise by the ratio 130/95. In the 5V supply, for instance, the following would happen: VAC = 130 x 9.27 = 12.7V 95 In the dual complementary +15 V supply: VAC = 130 x 19 = 26V 95 The increase in output must be absorbed by the regulator, which results in higher regulator power dissipation. The illustrated values are safe for the typical IC regulator but should be checked in any specific application. VNOM is VLOWLINE the ratio of the nominal AC line voltage to the required low line conditions. A sample illustration of the above will be shown for a supply requiring an output of 5V DC at 2A DC to operate down to an input voltage of 95V RMS. VOUT = 5V VREG = 3V VRECT = 1.25V VRIPPLE = 0.5 (1V p-p) VAC = 9.75 x 115 x 1 = 9.27 VAC 0.9 95 M2 Therefore, the transformer secondary voltage can be specified as about 18 V CT. For a bridge rectifier of the same output requirements, the only change is that: VRECT = 2 x 1.25 = 2.5V As a result VAC will be reformulated as: VAC = 11 x 115 x 1 = 10.46 VAC 0.9 95 M2 so that the transformer secondary voltage now becomes about 10.5V. Transformer Secondary Current The remaining step is to determine the transformer RMS secondary circuit. This can be accurately determined only by complex analysis. However, for practical engineering purposes the chart below may be used. 36 How to specify power transformer & filter ratings ADDITIONAL FACTORS TO BE CONSIDERED IN TRANSFORMER SELECTION Load Regulation Temperature Rise It has been assumed in the previous discussion of the In power transformers over 25VA, temperature rise change in transformer secondary voltage with line voltage that becomes a factor. The transformer may be constructed no change has been occurring in load current. Therefore, the with materials capable of withstanding higher temperatures transformers would seem to be ideal and the transformer and be a perfectly valid design. However, the extra power secondary voltage (VAC) will always be the same. Actually, dissipated may cause heating of nearby components. This all the voltages calculated are assumed to be full load. added power loss increases the total power dissipated in the Since transformers are not ideal and have an internal circuit area. The problem is not the internal temperature of impedance or "regulation" characteristic, variations in load the transformer, but the actual increase in watts lost. current may cause a problem. If the load should be "light" at Shielding "high line," then there will be an additional rise in secondary Certain AC power line noise and transients will be fed voltage, beyond that due to the rising line voltage, caused through to the transformer secondary because of the by the decreasing voltage drop in the transformer windings. capacitance between windings. This is a problem which is Most smaller VA transformers (<10VA) have a load very difficult to analyze. Whether or not it is a problem in a regulation of 20% or higher. This means that the transparticular applicaton can be best determined empirically. former no-load voltage will be 20% or more higher than If such feedthrough is a problem, the most common first rated full-load voltage. This must then be taken into step is to use an electro-static shield between windings. account in the calculation of maximum VAC (and DC This effectively reduces the inter-winding capacitance. voltage into regulator) with low-load currents. An equal and sometimes superior approach is to choose Due to the inherent design characteristics of transtransformers with non-concentric windings, i.e., with priformers, "regulation" will vary inversely with size (or VA mary and secondary wound side-by-side rather than one rating). In larger transformers size is determined primarily over the other. Both result in at least order of magnitude by the heat generated by internal losses. In smaller transreductions in capacitance. The "non-concentric" approach, formers (low VA rating) size is determined by the maximum however, gives superior reductions. It also results in higher permissible no-load to full-load regulation. Even though this insulation resistance and makes it simpler to obtain higher is an important design limitation, most transformer manuinsulation test voltages. Certain types of feedthrough cannot be much affected facturers do not publish load regulation data. The chart by the transformer design and other approaches such below tabulates load regulation for Signal standard as line filters or "MOVs" or ZNR's (transient surge transformers. suppressors) may have to be considered. It is possible to estimate the output voltage at intermediate loads since load regulation varies in an almost linear manner. Summary For example, the 241-8-16 has a full-load rating of 16 V @ This has been an attempt to provide a simple, practical 6.25 A and a regulation of 10%.

Dividing by 2.5 to convert from RMS ripple current to output current yields a maximum DC load current of 1.24 amps. Obviously either a large capacitor is required or ambient temperature must be reduced. As a final note, be sure to check whether the data sheet ratings are for still or moving air. Computer grade capacitors are often rated only for moving air. Other types may be rated for still air and are, therefore, actually more conservatively rated. Remember that capacitors are the number one cause of power supply failure. Don't let your supplies dominate the statistics column! Capacitor Selection For low current supplies (IOUT<IA) capacitor selection is relatively straight-forward. Capacitance is found by the simple formula: C = 1L x 6 x 10-3 V where: 1L = DC load current V = peak-to-peak ripple voltage ripple frequency = 120 Hz. This yields 2000 F/amp for 3V p-p ripple. At DC currents below 1 amp, capacitor heating is usually not a problem and peak-to-peak ripple voltage is the determining factor in capacitor size. At higher values of capacitance, where the ratio of capacitor outside surface area to volume is significantly lower, internal heating becomes a problem. Ripple current rating may be a determining factor in capacitor selection, rather than ripple voltage. In many cases, capacitor size will have to be increased to prevent excessive internal heating. Manufacturers' data sheets should be consulted (after an initial selection is made) to ensure that capacitor ripple current ratings are met. Remember that the RMS ripple current ratings shown on capacitor data sheets are not the same as DC load current. RMS ripple current in a capacitor input filter is 2 to 3 times the load current. In addition, the time-to-failure used to rate capacitors on data sheets is often 10,000 hours. For five-year life (40,000 hours), ambient temperature may have to be derated 30C from the date sheet rating. Capacitor life roughly doubles for each 15C reduction in operating temperature. The following calculations illustrate a typical design example: assume 1L = 3A, V = 4V p-p, VDC = 12V C = (6 x 10-3) (3A) = 4,500 F 4V Diode Selection The RMS value of the current flowing into a capacitor input filter is 2 to 3 times the DC output current because the current is delivered in short pulses. Assuming a full-wave center-tap or bridge, this means that although each diode is conducting only on alternate half cycles, it should be rated for at least the full output current. To ensure adequate surge capability during turn-on, a diode rating of at least twice the output current is recommended, especially for higher current supplies where the ratio of filter capacitance to output current is somewhat higher. Keep in mind that axial lead diodes achieve most of their heat sinking through the leads. Short leads soldered to large area standoffs or printed circuit pads are definitely recommended. For "short circuit proof" IC regulated supplies using three-terminal regulators, an additional diode derating may have to be used. Long-term output shorts do not harm the regulator, which goes into a current limit or thermal limit mode to protect itself. The diodes, however, may experience a substantial current increase during the short. Regulator data sheets should be consulted for current limit values, keeping in mind that current limit is a function of input-output voltage differential. At high input voltages, the short circuit current of IC regulators is often less than full load current, tending to alleviate this problem. METHOD OF DETERMINING SECONDARY CURRENT RATINGS The secondary currents shown in the tables are RMS ratings. Depending upon rectifier circuit configurations, the RMS secondary current is different from the DC output current. This is indicated in the chart below: RMS Secondary Current is = 0.7 x DC Amps Rectifier Type Filter Type Full-Wave Center-Tap Choke Input Full-Wave Center-Tap Capacitor Input = 1 to 1.2 x DC Amps Full-Wave Bridge Choke Input = DC Amps Full-Wave Bridge Capacitor Input = 1.6 to 1.8 x DC Amps For example, in a F.W. Bridge circuit with a capacitive filter, if the load is 1 Amp DC, the RMS Secondary current is 1.6 to 1.8 Amp RMS. 38
