Abstract:
An induction heating generator includes a rectifier circuit (10). Four capacitors (C1, C2, C3, C4) form a bridge circuit between two output terminals of the rectifier circuit (10). The bridge circuit includes a first capacitor series (C1, C2) and a second capacitor series (C3, C4). An induction coil (L) is interconnected in the center of the bridge circuit. At least two semiconductor switches (S1, S2) are connected in each case parallel to one of the capacitors (C1, C2) of the first capacitor series (C1, C2). The induction heating generator includes a control circuit block (14, 16, 18, 20, 22) for controlling the control electrodes of the semiconductor switches (S1, S2). A shunt element (SE) is connected in series with the first capacitor series (C1, C2).
