Im attempting to follow some of the multitude of h-bridge designs out there to create an inverter using power mosfets. While I can get the circuit to invert the polarity using the design in the first answer here: H-bridge - concern about mosfets, I'm only seeing .2v coming from a 24v supply. (I'm using IRF1405PbF n-channel and SUP53P06 p-channel fets) - from what I've read I'm not saturating them properly so they get hot and don't fully switch.
The outcome I'm after is to convert a DC voltage to AC at a higher than 50hz frequency in order to drive some Christmas light strings that have half the leds in each polarity without flicker.
Could anyone point me to a bridge schematic that would allow for a single PWM input (to control freq and most likely provided by a rasp pi). Or, anther way to generate a greater than 50hz AC supply from DC at around 24-30v/5A?
