The utility model provides an MOS tube rapid starting circuit, which relates to the technical field of electricity, and comprises a mains supply L and a mains supply N. One end of the mains supply L and one end of the mains supply N are provided with a fuse F1, a bridge rectifier BR1, a resistor R1, a resistor R2, a resistor R3, a field effect transistor Q1, a voltage stabilizing diode Z1, a diode D1, a diode D2, a capacitor C1, a transformer T1B winding and a network VCC. When a mains supply L and a mains supply N are connected, a resistor R1 turns on a field effect transistor Q1, current passes through a resistor R2, the field effect transistor Q1, a diode D2 and a resistor R3 to quickly charge a capacitor C1, the voltage of the capacitor C1 quickly supplies power to a control IC, the purpose of quick starting is achieved, after the circuit is started, a winding of a transformer T1B charges the C1 through a diode D1, the voltage can be higher than the voltage of Z1, the field effect transistor Q1 is turned
