Abstract
In a method for operating a plasma installation, an induction heating installation or a laser excitation installation in a pulsed power output operation, includes controlling at least one semiconductor switching element to produce a power loss in the at least one semiconductor switching element during a pulse pause time period in a pulse pause operation during which no power suitable for the ignition or the operation of the plasma process, the induction heating process, or the laser excitation process is produced at a power output of a power generator by the at least one semiconductor switching element of the power generator, and such that a reduction of a temperature of the at least one semiconductor switching element by more than a predetermined value is prevented.
