ZVS with better gate drive

I wanted to see if there was a better way to drive the gates of my fets I wanted to use multitable parallel fets 4 fets per side of cap bank the original circuit couldn't drive the fets fully on this circuit uses 2 opamps as comparators

Regular comparators wouldn't work, too little output current

So I should use fets to drive the gates on and off

idea is getting better, but yeah the gate drives still need a hell of a lot of power

The thing is the mazilli zvs driver was made to have a nearly perfect zero voltage switching effect, so anything you add to drive the MOSFETs, such as your comparators, is going to add a little bit of delay, shifting the switching moment to a point were the voltage is not zero any more, thus lowering efficiency and stability
