It looks like it might work at first glance, but it’s so badly designed that the gate drive resistance is too high and the oscillator will not work as-is. The basic idea of this push-pull inverter is fine and the MOSFETs chosen seem OK, but the control circuit is highly flawed. I’m an expert power inverter engineer and I can tell you with authority. I tried to simulate the oscillator and it doesn’t work without a lot of modification. The gate drive resistance should be less than 100 ohms and it’s in the KOHM region. The designer is using 2-input NOR gates, some with one input grounded and others with both inputs tied together. Either way, they act as a simple inverter, so why two distinct connection types? The control will not produce a PWM output even if the oscillator did work (which it does not).
Anyone would be much better off using an SG3526 IC from Microsemi or even a SG3524, but the latter will need a means of active gate drive which the former has a dual gate drivers built-in. The oscillators are stable and it has a means for over current protection.
