What kind of signals do PA2 and PA3 give, so that VOUT can output a voltage of about 50V? And the waveform is controllable (pulse width, frequency, period, amplitude, etc.) VO1 and VO2 are differential signals?

The 50V is mainly provided by your step-up part.

The output depends on your H-bridge drive waveform. You can use direct PWM complementary drive, or SPWM to fit the required "shape".

Can you provide a reference circuit or connection for the drive and output control?
