Abstract
The present invention provides a magnetic low voltage dimmer circuit that reduces DC magnetizing current which may be present in a dimmer system. The dimmer circuit delivers an RMS value of an AC supply voltage to a load while preventing or reducing a DC magnetizing current from damaging the dimmer circuit and/or load. The dimmer circuit includes a shutdown circuit which detects whether a DC voltage, corresponding to the DC current, is present across a circuit component and whether the DC voltage has reached or exceeded a predetermined voltage reference level, rendering the component non-conductive and thus preventing the DC magnetizing current from flowing through a load.
