Hi,check my simple driver,not best but good enough
Place 2R2 in series with diode on 12V,to limit current peaks.
What about reversed PNP?It works well with split supply in simulation,with very hard to drive mosfets,but i dont like the 8 A on d4 in my schematic,i would dissipate more power than anything
Yes,it will dissipate more than fets
I'll try another idea...
And maybe IR2184 with separated power for upper and lower fet (small flyback smps)...I dont think there are better options than gate drive transformer
Check my new progress
Class D on +/-56V 500W SMPS working now,with feedback,offset 1,8mV
Do any interested
First pic. voltage measuring. (Left meter lies,chinese s*it) Both voltages is same.
Last pic. offset
Second pic. wave after totem pole
Third pic. is voltage at drains of fets.
Fourth pic. is voltage at SMPS transformer.
