Half bridge in "A reliable plasma speaker doesn't work"?
However, after I finished, it didn't work. I used an oscilloscope and I found the VGS of high side MOSFET was between -3 and -6, and the low side was between 12 and 0. Then I accidentally got it work, but the MOSFETs were very hot, and then they exploded. After I change the MOSFETS, it had the same problem as before again. But if I short the capacitors, the wave form for both the high and the low were correct. can anybody explain why? Thanks.
