Work of the circuit
The circuit consists of AC pressure regulating circuit and rectification circuit. (It is showed in picture 9-35.)
Turn on switch S1. 220V AC separates into 2 parts. One charges C1 after being adjusted. And the other one changes into DC voltage and works as M’s working power. When the voltage of C1 reaches a constant value M starts working.
