ePWM1A and 1B configuration

Other Parts Discussed in Thread: TMS320F28027

Hi!

I am trying to handle ePWM1A and 1B independently, i.e. When an even occurs, I need to make "ePWM1A" LOW and a PWM waveform of 20KHZ on "ePWM1B".

is it possible to do it in piccolo (TMS320F28027)? Whatever information I read regarding this, the documents are saying as ePWM1A-1B are complementary to each other. But is it the case every time? can I do something like this using a Trip Zone mode of ePWM module?

Please help me!

Thanks in advance.

    Yes, it is very much possible. Refer page number 84 of ePWM module user guide for all the details.
