// Run Time (Note: Example execution of one run-time instance)
//=========================================================
EPwm1Regs.CMPA.half.CMPA = 700; // adjust duty for output EPWM1A
EPwm2Regs.CMPA.half.CMPA = 700; // adjust duty for output EPWM2A
EPwm3Regs.CMPA.half.CMPA = 500; // adjust duty for output EPWM3A
15.2.3.4 Controlling Multiple Buck Converters With Same Frequencies
If synchronization is a requirement, ePWM module 2 can be configured as a slave and can operate at
integer multiple (N) frequencies of module 1. The sync signal from master to slave ensures these modules
remain locked. Figure 15-58 shows such a configuration; Figure 15-59 shows the waveforms generated by
the configuration.
