I have a modulating sine wave signal of 50Hz and triangular wave carrier signal of 2.5kHz, now I want to generate four spwm gating signals for four IGBTs of the H bridge inverter from my MSP430g2553. I could generate two signals using two Timers of A (A0 and A1) but I am being unable to program my msp to generate four signals (picture given below). Can you please suggest me any logic to generate my four gating signals from a single MSP? Please Help!all_about.png
