Create 3 pwm signals with 120° using only one timer

LRomb.2 · ‎2023-01-05

Hello,

I'm using a NUCLEO-G431KB to create the PWM signals.

I need to have 3 PWM signals plus their complementary outputs with same pulsewidth and a phaseshift of 120° between them, see picture below.

In the video Hands-On with STM32 Timers: Internal Triggering System, three timers are used via master-slave mode to get this done.

Is it possible to create these three signals with one Timer, for example TIM1 and use CH1-CH3 and their complementary outputs?

Thanks!
