Just discovered another interesting features of the "Advanced Timers" in the STM32G4: 3-phase combined PWM. Essentially it takes timer channels 1, 2, and 3 and ANDs them together with channel 5. On the one hand this sounds like it's kinda useless: why would you want to modify your PWM waveform during 3-phase commutation?
|Top three traces: PWM for CH1-3, bottom channel shows output from CH5 (well, CH4 since CH5 doesn't have pin-mapped output)|
Turns out, it's a really interesting way to add deadtime to a PWM signal without worrying about maximum duty cycle limits. In fact, you can crank the duty cycle all the way up to 100% and you'll still get center-aligned deadtime!
|CH3 is "100% duty cycle" according to its the timer configuration, but it still has deadtime to do ADC sampling.|
That's *super* useful for ADC sampling, which, as it turns out, is my next target. Stay tuned...

Thanks for sharing, but I am a little confused. First you said that CH5 is being ANDed and then you show CH5 as the output, which it can't because when CH1-3 are low CH4 is high. Do you mean NAND?ReplyDelete
