I have design this Hbridge circuit with the help of the forum members, now I want to use the same bridge circuit for battery charging with current sensing on the primary side of the transformer using C.T (current Transformer). I want to know which mosfets to keep pulsating and which to keep on, I dont want PFC feature which may complicate the coding and hardware.
my little knowledge says that I have to keep the upper (high side Mosfets) off and keep pwmming the lower mosfets, but is necessary for me to detect the zero crossing or not.
and what are the maximum and minimum duty cycles.
