The circuit has a rectified mains circuit (1), and first and second switching elements (6,7) connected in series between connection bars (4,5). A resonance circuit is connected between two terminals of the second element (7) and has an induction heater winding (11) and a resonance condenser (12). There are also switching and heating controls, and a damper circuit (34) to reduce switching losses.
