I made an experiment for 100W wireless power transfer for my research. I used IR21844S for half bridge converter using IRFP360 MOSFETs. I designed the transmitter and receiver coils. I used full bridge rectifier using 1N4002 diodes and 2.2uF filter capacitor. I tested 10.5 ohms as a load by using an electronic load and measure voltage and current. I gave 24V dc supply for MOSFETs and 15V for gate driver. But the problem is that there is no current from the supply for MOSFETs and the power at the load is not even 0.1W. I planned to use schottky diodes in parallel with MOSFETs to reduce voltage spike and change schottky diodes in the rectifier of the receiver circuit. I used the frequency around 80kHz. I have no idea where I have the problems. I also simulated using LT spice and the simulation results are not that bad. Can someone help me or suggest any ideas?
