I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Abstract: Teaching scientific concepts to undergraduate students is quite difficult sometimes especially when lots of mathematical terms are involved in the teaching process. Frequency modulation is ...

Abstract: This paper proposes an evaluation model for PWM carrier loss in claw-pole machines employed for ISG applications under dual three-phase drive. The PWM carrier loss is evaluated based on PWM ...
