Source: InternetPublisher:睡不醒的小壮 Keywords: Controller circuit refrigerator rectifier filter Updated: 2020/11/13
Circuit working principle: AC 220 V voltage is current-limited and stepped-down by C1 and R1, rectified by
VD1~
VD4 , and filtered by C2 to obtain 9V DC voltage for the relay K coil to work.
Zener diode ZD and resistor R10 form a 5v voltage stabilizing circuit to power the MX0230.
