![]() Remember that the output of the transformer will be high frequency AC (50kHz square wave in this case). Output voltage of the DC-DC converter stage will be 310V. Let's say the ferrite transformer will be used in a 250W inverter. For explanation, I'll use an example and go through the calculation process. ![]() Calculation of required turns is actually quite simple and I'll explain this here. For transformer design, the difference between a push-pull and a full-bridge transformer for same voltage and power will be that the push-pull transformer will require a center tap, meaning it will require twice the number of primary turns as the full-bridge transformer. In this situation, there are really only two choices when selecting topology – push-pull and full-bridge. In a high-frequency/SMPS inverter, the ferrite transformer is used in the step-up/boost stage where the low voltage DC from the battery is stepped up to high voltage DC. On different forums, I often find people asking for help in calculating the required turns for a ferrite transformer they are going to use in high-frequency/SMPS inverters.
