More Information
Summary:	A power supply device for a non-linear load, especially a magnetron for microwave ovens, includes a resonant transformer. Using a fuzzy logic management unit, a level of a low voltage signal on the primary side of the transformer, a level of high voltage signal on the secondary side of the transformer, and a signal corresponding to the ambient temperature of the transformer are taken into account for the generation of a parameter for a control signal for controlling a switch positioned at the primary winding of the transformer. The power supply device makes it possible to reduce the size of the resonant transformer.
