CONTROL CIRCUIT FOR AN INCANDESCENT ELEMENT

摘要

The proposed control circuit for an incandescent element serves to regulate the electrical heat energy of an incandescent element used in particular for auxiliary heating systems in vehicles. The control circuit is provided with a switching device which switches on and off alternately in a modulated and timed way the supply voltage and is situated between the supply voltage connection (V+) on the high potential side and the incandescent element (G) which can be made without a regulating filament.
