Abstract：Losse of 10kW high-capacity high-frequency transformer made of copper foil winding is analyzed by finite element method. For different transformer winding structures, the interleaved winding technology can reduce loss of high-frequency transformer by use of simulation and experiment. The final prototype experimental data provide strong evidence. A 10kW high-frequency transformer prototype at 20kHz employed the interleaved configuration is 99% efficiency achieved.
