1 Introduction

The Evaluation Driver Board 2ED100E12-F2 for EconoDUAL™3 modules as can be seen in Figure 1 and

the Evaluation Driver Board 6ED100E12-F2 for EconoPACK™+ modules, shown in Figure 2, were

developed to support customers during their first steps designing applications with these modules. The basic

version of each board is available from Infineon in small quantities. The properties of these parts are

described in the chapter 2.2 of this document whereas the remaining paragraphs provide information

intended to enable the customer to copy, modify and qualify the design for production, according to his

specific requirements.

The design of the 2ED100E12-F2 and the 6ED100E12-F2 was performed with respect to the environmental

conditions described as design target in this document. The requirements for leadfree reflow soldering have

been considered when components were selected. The design was tested as described in this

documentation but not qualified regarding manufacturing and operation in the whole operating ambient

temperature range or lifetime.

The boards provided by Infineon are subjected to functional testing only.

Due to their purpose Evaluation Boards are not subjected to the same procedures regarding Returned

Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular

products.

See Legal Disclaimer and Warnings for further restrictions on Infineons warranty and liability.

of the IGBT module.

3 Application Note

The following chapter describes the board´s operation in evaluation setup. Please note that the following

paragraphs describe the circuits of the 2ED100E12-F2 which has been modified (compared to the last

revision of this AN) to drive IGBT4 modules and to reduce the susceptibility to erroneous triggering of the

Vcesat-detection. Same changes may also be applied to the 6ED100E12-12-F2, but layout and part list of this

board provided in chapter 7 still represent the initial design.

3.1 Power Supply

The 2ED100E12-F2 and the 6ED100E12-F2 have an integrated DC/DC converter for each leg, which

generates the required secondary isolated unsymmetrical supply voltage of +16 V / -8 V. Top and Bottom

driver voltages are independently generated by using one unipolar input voltage of 15 V. Additionally, the

power supply is protected against gate – emitter short circuit of the IGBTs. In case of DC/DC converter

overload, the output voltage drops. This Under Voltage Detection function insures gate voltages within

specified range. The fault is reported to the driver’s primary side.

3.2 Input logic – PWM signals

The Evaluation Driver Boards are dedicated for a half-bridge EconoDUAL™3 and sixpack EconoPACK™+

IGBT configuration, therefore it is necessary to connect two separate PWM signals or 6 separate PWM

signals. Individual signals for Top and Bottom IGBT are necessary if there is a half-bridge module or rather 6

dedicated signals if there is a sixpack module. The schematic for a single driver is depicted in Figure 6. The

signals need to have the correct dead time. Both Evaluation Driver Boards do not provide automatic dead

time generation and recommended minimum dead time tTD is 1 µs, provided gate resistors like suggested in

tables 5 and 7 are used. If larger gate resistors are used please refer to [1].

Figure 6 Schematic detail of the input circuit for a single driver.

The schematic in Figure 6 shows driver circuit with positive logic. IN+ is used as signal input whereas IN- is

used as enable signal. Therefore a +5 V signal on the IN+ input pin and a GND signal on the IN- input pin is

necessary to switch on the IGBT. To operate the whole circuit with negative logic the capacitors on the input

pins have to be exchanged. Otherwise this would cause an additional delay. IN+ will then operate as an

enable signal.

3.3 Maximum switching frequency

The IGBT switching frequency is limited by the available power and by PCB temperature. According to

theory the power losses generated in gate resistors are a function of gate charge, voltage step at the driver

output and switching frequency. The energy is dissipated mainly through the PCB and raises the

temperature around the gate resistors. When the available power of the DC/DC converter is not exceeded,

the limiting factor for the switching frequency is the absolute maximum temperature for the FR4 material. The

allowed operation temperature is 105 °C.

Generally the power losses generated in the gate resistors can be calculated according to formula (1):

gesoutRgRgextdis QfVPPP ⋅⋅∆=+= int (1)

In this formula s

fresembles the switching frequency, out

V∆represents the voltage step at the driver output

dis

P is the dissipated power, ge

Q is the IGBT gate charge value corresponding to -8/+16V operation. This

value can be approximately calculated from the datasheet value by multiplying by 0.8.

Most of the losses are shared between the internal – intRg

P and the external – Rgext

Pgate resistors.

Negligible losses are also in the driver IC itself. Due to the PCB temperature criteria the power dissipated in

external gate resistors gext

P is to be considerd for the thermal design. Temperatures can be calculated

takeing relevant thermal resistances of this part of the board into account.

Based on experimentally determined board temperatures the following thermal resistances have been

calculated using an equivalent circuit diagram as given in Figure 7:

Gate resistors to baseplate: RthB-G = 45 K/W

Gate resistors to ambient: RthR-A = 39 K/W

Using these values and the equivalent circuit, it is possible to determine the maximum board temperature, if

The maximum switching frequency will be determined when either the maximum allowable board

temperature has been reached (105°C) or when the limit of power transmission of the DC/DC converter (1.5

W per channel) is exceeded.

3.4 Booster

Two complementary pairs of transistors are used to amplify the driver ICs signal. This allows driving IGBTs

that need more current than the driver IC can deliver. Two NPN transistors are used for switching the IGBT

on and two PNP transistors for switching the IGBT off. Resistors in the individual base connections ensure

proper parallel operation.

The transistors are dimensioned to have enough peak current to drive all 600 V and 1200 V EconoDUAL™3

and EconoPACK™+ modules. Peak current can be calculated like in formula (2):

Figure 8 Booster

Gate resistors are connected in between booster stage and IGBT module gate connection. Suggested

values are provided in tables 5 and 7. For some modules the value for these resistors is 0 Ohm. In this case

just a jumper is required. If resistors are needed ensure that these resistors have a suitable rating for

repetitive pulse power to avoid degradation.

3.5 Short circuit protection and clamp function

The short circuit protection of the Evaluation Driver Board basically relies on the detection of a voltage level

higher as 9 V on the DESAT pin of the 1ED020I12-F driver IC and the implemented active clamp function.

Thanks to this operation mode, the collector-emitter overvoltage, which is a result of the stray inductance and

AN2008-02

Driver board for EconoDUAL™3 and EconoPACK™+

Application Note

Application Note 13 V1.2, 2009-08

the collector current slope, is limited. Depending on the stray inductance, the current and the DC voltage the

overvoltage shoot during turn off changes.

Figure 9 shows the parts of the circuit needed for the desaturation function and the active clamping function.

Figure 9 Desaturation protection and active clamping diodes

In case of a short circuit the saturation voltage GE

Uwill rise and the driver detects that there is a short circuit.

The IGBT has to be switched off. There will be an overvoltage shoot due to the stray inductance of the

module and the DC-Link. This overvoltage shoot has to be lower than the maximum IGBT blocking voltage.

Therefore the evaluation driver board contains an active clamping function whereby the clamping will raise

the voltage for the booster and also raise the voltage directly on the gate.

The typical turn-off waveform under short circuit condition and room temperature of a FF450R12ME4 module

without any additional function is shown in Figure 10a.Typical waveform under short circuit condition with

active clamp function is shown in 10b at room temperature.

3.6 Fault output

When a short circuit occurs, the voltage UCE is detected by the desaturation protection of the 1ED020I12-F

and the IGBT is switched off. The fault is reported to the primary side of the driver as long as there is no

reset signal applied to the driver. The /FAULT signal is active low, the according schematic can be seen in

Figure 11.

3.7 Temperature measurement

Based on the NTC built into both module types, the Driver Board offers IGBT base plate temperature

measurement in the range of -40 °C…150 °C. The Evaluation driver boards work with a Sigma/Delta

converter. Thus a digital signal is provided. This has the advantage that a normal I/O Pin on the

microcontroller can be used and that the subsequent error is low. However an analog signal can be

produced with the use of the following schematic.

Switching losses

Application Note 16 V1.2, 2009-08

Using the baseplate temperature and a thermal model the junction temperature can be estimated. The

complexity of the thermal model needed for this purpose depends on application and heatsinking conditions

as well as on requirements on accuracy and dynamic response. In case of a broken wire the output switches

down to 0 V. Output voltage vs. baseplate temperature is shown in Figure 14, assuming that the circuit

according to Figure 12 is used to convert the digital signal to an analog signal.

Switching losses

Application Note 17 V1.2, 2009-08

4 Switching losses

The setup used for preparing this application note varies from the setup used to characterize the devices in

three aspects:

DC-link inductance:

The DC-link inductance of the setup used for these test is has a value of approximately 35 nH for all modules

investigated here in contrast to varying values between 35 nH to 80 nH used for device characterization (see

device datasheets for details). For a detailed discussion on the impact of DC-link inductance on switching

losses please refer to [2].

Gate voltage:

This Evaluation Board provides a gate voltage of -8 V for turning off and 16 V for turning on wheras

charactization is done with a driver providing +/- 15 V of gate voltage.

Gate driver output impedance:

According to IEC 60747-9 for characterization of an IGBT the driver used should resemble an ideal voltage

source as far as possible. For the Evaluation Board a driver output stage has been choosen that considers

board space as well as cost constraints. Therefore it can not provide close to zero output impedance.

All aspects discussed above have an impact on the switching speed of the module and hence also on the

switching losses. Gate resistor values have been choosen so that di/dt at turn-on compareable to

characterization has been achieved. Nevertheless small deviations in the turn-on losses persist. For the turn-

off losses there is little impact of driving conditions for trench-fieldstop IGBTs like the ME3 and ME4 devices.

For NPT IGBTs, like used in the MS4 modules, the considerations made for turn-on losses also apply for

turn-off losses.

4.1 Turn-on losses

The turn-on losses are expected to be close to the values of the datasheet of the modules. As an example

the turn-on losses for an EconoDUAL™3 FF450R12ME3 as well as for a FF450R12ME4 module are shown

in the following diagrams.

In general the turn-off losses increase linear with the DC-Link voltage. In the case of the driver board it does

not increase linear because the active clamping function increases the turn-off losses due to a decrease of

the di/dt.
