Requirement: 8 pwm of 50 Hz and 4 pwm of 100kHz.
4 of the 50Hz pwms are complementary((1a,1b),(4a,4b),(5a,5b),(6a,6b)) to each other and should be synchronised(1a,4a,5a,6a).
2 pwm of 100kHz are complementary to each other((2a,2b),(3a,3b)).
epwm 2a and 3a are of 50 percent duty and epwm 3a will be sinusoidally phase shifted with respect to 2a to achieve a 50 Hz sinusoidally modulated waveform.
Problem:I have to synchronise starting of epwm 2a(100kHz) and 1a(50Hz),but epwm 3a should be phase shifted with respect to epwm 2a
How to do this?
