摘要: A smart dimmer for control of a lighting load from an AC power source can replace any switch in three-way or four-way system. The be connected on the line-side load-side system with standard other location. According to one embodiment present invention, includes two triacs intensity load. preferably gate drive circuits coupled gates rendering conductive each half-cycle source. include sensing detect whether currents are flowing after rendered conductive. controller is operable determine state response current not flowing.
