Inquiry on STM Controllers with Sinusoidal PWM Capability for Dual H-Bridge Applications

[sonaliz]

Hello,

Can you please check if STM manufactures controllers with Sinusoidal PWM, our requirement is to drive 2 H-bridge full drivers, so if they are available please let me know.

 

Thanks,

Sonali

Hello,

There is no feature called "Sinusoidal PWM" on STM32 but you can generate sinusoidal with a timer PWM output.

You can refer to this article:

Watch also this video: https://www.youtube.com/watch?v=4omSQHY0rDw

You can also use DAC to generate sine wave:

Hope it does answers your question.
