Zusammenfassung:	The invention belongs to the field of aviation airborne power supply systems, and relates to a power supply control box EPU starting control method and circuit. The control circuit comprises a main alternating current contactor state output circuit, a main direct current contactor state output circuit and a field effect transistor VT1, wherein the main alternating current contactor state output circuit is used for outputting a high level when a main alternating current contactor is disconnected; the main direct current contactor state output circuit is used for outputting a high level when the main direct current contactor is disconnected; when the main alternating-current power generation system breaks down, the main alternating-current power generation system state signal output end outputs high level, the two contactor state output circuits are connected to the main alternating-current power generation system state signal output end through backward diodes, and the combined main alternating-current power g
