Pre-charged control circuit

The utility model discloses a pre-charged control circuit, which comprises an electrolytic capacitor (C), a charging resistor (R charging), a key (KEY), a relay (M), a battery (Battery). The control circuit is characterized in that the field effect transistor (Q1) is serially connected between the charging resistor (R charging) and the electrolytic capacitor (C), which is used for pre-charging the large-capacity capacitor in the circuit and controlling the time of power-on of the main switch circuit, so that the safety and the reliability of the whole circuit is effectively guaranteed.
