    Neither circuit will function as intended. In the upper circuit, each bipolar transistor base has a MOSFET gate connected to it. This means the gate never will have more than 0.7 V on it, and this is not enough to enhance it. In the lower circuit, the two oscillator transistors are not cross-connected correctly. For example, C3 connects the two bases, rather than connecting one base to one collector. Also, the oscillator collectors can not get much above 0.8 V because they are clamped by the power transistor base-emitter junctions.

    Even with all of these errors corrected, the circuit you have chosen is a difficult one to get working properly. It is a very difficult project for a beginner.

    Is there a problem with using a normal off the shelf PWM driver IC like a SG3524 or such to make a basic yet actually functional power inverter? o_O
