Supply circuit adapted to supply a magnetron (1) and comprising a high loss inductive voltage increasing transformer (8) whose primary winding (13) is mounted in series with a commutation element (14) adapted to chop the voltage and whose secondary winding (19) is connected to the load (1). The circuit comprises also a self inductor (17) mounted in series with the primary winding (13) of the transformer (8), as well as a condenser (18) connected in parallel to the primary winding. The commutation element is a unidirectional current gate (14), and the secondary winding (19) of the transformer (8) is directly connected to the load (1). The circuit is useful, for example, in microwave ovens.
