This series of transformers was designed for (but not limited to) single and two switch forward converter applications. The power levels stated are for actual demo boards typically operating between 200-400kHz with 100-200LFM of airflow. Other turns ratios and auxiliary windings may be available. Please contact Pulse Power Applications Engineering for details. 2. The leakage inductance is measured at the primary terminals with all other windings shorted. 3. The listed transformers are designed to meet basic insulation (1.4mm creepage and clearance with 1500Vdc isolation). Lower cost transformers with operational insulation (1500Vdc isolation with no creepage and clearance spacings) are available. Please contact Pulse Power Applications Engineering for details. 4. To determine if the transformer is suitable for your application, it is necessary to ensure that the temperature rise of the component (ambieint plus temperature rise) does not exceed its operating temperature. To determine the temperature rise of the component it is necessary to calculate the total power losses (core and copper) in the application. Total Copper Losses (Pcu total(W)): Pcu total(W) = sum of the losses in each winding The losses in each winding can be calculated by: Pcu(W) = .001* DCR(m) * (Irms2) Core Losses (Pcore(W)) To calculate core loss, use the following formula: CoreLoss (W) = 1.589E-13 (B)2.5 * (Freq kHz)1.8 where: B = 179211.46 * Vin min * Dutycycle max / (Freq kHz * Primary Turns) Total Losses: P total = Pcu total + CoreLoss Temperature Rise: The approximate temperature rise can be found by looking up the calculated total losses in the temperature rise vs. power dissipation curve.
