What do you mean by:

It is advisable that you switch the top 2 MOSFETS on and off for the complete cycle .
always On or OFF? or driven by an inverted version of the PWM signal driving the lower MOSFETs? the first will reduce the switching losses but not the power losses, and if I want to work with a motor of 12V, 20Amps at 20KHz, those are way bigger, and that is why I was trying to implement a 4 PWM control solution.
