发明名称 Inductive load sensor for dimmer circuit
摘要 A lighting control circuit includes a dimmer circuit which is provided for an electrical outlet. An inductive load detection circuit is provided for identifying the presence of an inductive load in the electrical outlet. When an inductive load is sensed, dimming of the power directed to the electrical outlet is stopped such that full power is delivered to prevent damage to the load. The inductive load detection circuit identifies the presence of an induction load by sensing voltage spikes. In one embodiment, diodes which have a high impedance at lower voltages, but are largely conductive at higher voltages are utilized to achieve this control.
