I am playing around with a Mosfet H-Bridge to switch 125kHz signal through a load. The circuit has P-Channel on high side and N channel on bottom of the arms. The Fets are controlled by Mosfet drivers. I also have some fets switching the series load resistance to change power electronically.
The issue is that the P-Channel devices are not switching off fast enough and therefore still on when N channel on same arm is switched on, causing excessive current drain.
Let me know if you have experience with MOSFETs used in this type of switching application and I can post the circuit and part numbers of devices used.
Thanks in advance.
