Transformerless Power Supplies: Resistive and Capacitive

Transformerless Power Supplies: Resistive and Capacitive There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier circuit. There are also switch- ing power supply solutions, however, in applications that involve providing a DC voltage to only the microcontroller and a few [...]
