I want to generate SPWM wave with 20KHz switching frequency and 50Hz modulating signal frequency. I am using F28335 ePWM block in simulink to do that. That block has duty cycle as input parameter. For SPWM wave, duty cycle should continuously vary, in perticular pattern. can any one suggest some logic to do that.any general logic will help(other than simulink blocks) . p.s. need logic to vary duty cycle of ePWM block in simulink to get SPWM(sinusoidal PWM) signal on F28335 board. any general logic will also help.(other than simulink blocks)

I'm having the same issue. Were you able to get it working?

Me too, are you solve this working?

use the CMPA register in the ePWM module to change the duty cycle of the PWM
