I used IR2110 for half bridge in wireless charging project. I got a very high voltage spike in transmitter coil. I used arduino uno for signal of IR2110 and one common ground for VDD, VCC, Arduino and DC voltage supply. I also tried UF4007 in parallel with MOSFETs and also used snubber RC in parallel with MOSFETs but it does not reduce any voltage spikes. And also HO voltage is a little bit lower than LO. What should I do? Can anyone suggest me?
