发明名称 LOAD CONTROL DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a load control device capable of realizing stable load control by preventing erroneous operation of a load due to small current passing through a snubber circuit at the inoperative time of the load. SOLUTION: This load control device includes the load and a power control element connected with an AC power supply in series, and the snubber circuit connected to the power control element in parallel. A restraint means is provided to restrain current passing through the snubber circuit at the inoperative time of the load. A switch for cutting off current passing through the snubber circuit at the inoperative time of the load is provided in series to the snubber circuit. The snubber circuit is constituted of a thermistor having a negative temperature coefficient. COPYRIGHT: (C)2004,JPO
