SPWM with F28335 and DMC library

Gabriel Mejia

good afternoon

I need the algorithms to generate SPWM signals with F28335 DSC, this algorithms I will allow to control a full bridge single phase. I can please indicate:

1. which function in the DMC (Digital Control library) library, do I allow SPWMto do?

2) what another alternative, do you propose me ?

thanks

Hi Gabriel,

I'm bit confused here, are you talking about Sine or Synchronized PWM; I guess its Sine PWM right? Please confirm this so that I can help you out accordingly!

Regards,

Gautam

thanks for the fast answer. I need to program the sine pulse width modulation (SPWM), for the control of a full bridge monophasic of IGBTs. Which funtion in the DMC library, help me?

Thanks Gautam

Hi,

You can implement a SPWM without any libraries too, using sine cosine equations and a lookup table. Else you can also make use of IQMath library for getting sine values. Search this forum thoroughly, you'll find your answer!
