I am looking at doing a multi-purpose experimental battery charger board. (M-PEBCB).
I use a 48v battery grid to run my house. It is 8 strings of 27M deep cycle Sears Die Hard. I am looking to do a 100A/48V charger w/PFC. I also have a 12v charger that needs a controller and I would also like to experiment with MPPT algorithms.
I intend to use a PIC to develop the current command signal. PIC will have all the hooks for current and voltage sensing. I am looking for some kind of PWM chip to follow the pic.
I would like just a controller with one PWM output to run a buck with synchronous rectifier. I will level shift and do gate drives separate. I think a 8pin part should be able to do what I want.
