Abstract :
A local power supply circuit which is driven by the main switch of a PWM power converter is described and analyzed. The operation of the circuit is based on the charge pump principle with a resonant reset of the charge pump capacitor. The charge pump capacitor also serves as a turn off snubber of the main switch. The analytical derivations are verified by experimental results
