1. An MF power generator for induction heating or a plasma process, the MF power generator comprising:

  • a DC current supply;

    an inverter comprising at least one switching element connected to a first polarity current supply potential of the DC current supply; and

    an output network connected to the inverter;

    wherein the inverter comprises a decoupling circuit for each switching element for decoupling the switching element from a voltage of the output network;

    wherein the decoupling circuit comprises;

    a first component connected in series between the switching element and an input terminal of the output network; and

    a second component connected between the switching element or the input terminal of the output network and a limiting potential differing from the first polarity current supply potential.
