Hello Gentlemen,
I am looking for some clarifications on using this micro for a modified sine wave inverter (basically a square wave which has dead bands between the positive and negative cycles). The configuration is a center tapped transformer switched to ground with 2 MOSFET banks.
I chose this micro since I can get a 50Hz complementary PWM from a 20MHz crystal operation in PCPWM mode using the prescaler and postscaler.And also because it is possible to program dead bands between the 2 complementary PWM outputs.
I hope someone can vet my assumptions.
Does a Center Aligned output mode mean that the PWM ON time will be centered at the mid point of the PWM period and not just begin at the mid point of the PWM period ? If so that would make it ideal for this kind of application.
TIA.
