Complementary PWM generation

Bhavani_Bhagyasree — Wed, 26 Apr 2023 12:30:23 GMT

I want to generate 3 (min) pairs of Centre - aligned complementary PWM signals with S32K3 series. Is it possible? If so how? I saw that complementary PWM is generated with eMIOS, TRGMUX and LCU combination. I understand that Centre-Aligned PWM is possible with 7 channels of eMIOS, TRGMUX and LCU have 4 outputs. Is there any possible way to implement my requirement?

Hi @Bhavani_Bhagyasree

I suggest you take a look at the application note: 3-phase Sensorless PMSM Motor Control Kit with S32K344 using RTD Low-Level API. Where it is show how to generate a center-aligned PWM functionality, realized by modules eMIOS, TRGMUX and LCU.

It will be useful for you.
