Sorry, mode 2 still isn't clear to me.... "2. Bipolar voltage on the load with a rate of 0-50 Hz"
Do you mean...
A) That polarity of the voltage across to the load is switched at 0-50Hz (and...

Ah, I didn't quite get you wanted locked antiphase PWM, ie the polarity of bridge is "reversed" every PWM cycle.
I thought you wanted to run it "forward" for x ms and then "in reverse" for x ms...
I'm probably missing something...
Why not simply turn on the lower MOSFET in question, apply your 1kHz PWM signal to the (correct) upper MOSFET and then modulate it using your 0-50Hz signal. In...
