i am doing a solid state high frequency welder. i am using a ferrite core transformer. i have wound the transformer with 106 turns in the primary and 10 turns in the secondary. i want to test it with 5 khz, 324 volts on the primary and approximately 150A current in the secondary. how should i go about the testing and also how do i calculate the temperature produced for 150A current? Also i need to find the core losses. please help me out.
