Hi all,
Has anyone got any idea for high speed switching for power mosfets ? a typical mosfet has like 3,000pf gate capacitance and my driver can just about cope with 1mhz, but 2mhz my drive wave appears like a sawtooth wave, so the mosfets never really hit fully on or so, so they heat up like hell... Theres some small info on using a class C and class E design though I dont have any experiance in these, I think the class c design is for ham radio users driving up into the 10mhz range...
If anyone can suggest something to look into then this would help me out...
thanks, chris
