In this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...
This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A) in a diode bridge is used to control the voltage across an ...
