The utility model relates to an alternating current-direct current detection control circuit connected between equipment to be tested and a lighting surge test instrument. The control circuit comprises an alternating current-direct current detection sub-circuit, a CPU (central processing unit) control sub-circuit and a sampling control sub-circuit, wherein the detection terminal of the alternating current-direct current detection sub-circuit is connected with a power supply of the equipment to be tested, the output terminal of the alternating current-direct current is connected with the CPU control sub-circuit, and the CPU control sub-circuit is connected with a synchronous sampling sub-circuit of the lighting surge test instrument by adopting a control sub-circuit. Compared with the prior art, the alternating current-direct current detection control circuit has the advantages of being convenient and reliable and the requirement that equipment in different power supply types is tested can be met by adopting only one instrument.
