Definitions

Switching period S is understood here to mean the period of time during which the semiconductor switch is once in its conductive and the subsequent blocked state.
Periodically alternating current is understood to mean both pulsating direct current and alternating current and combinations of the two, an assigned frequency being in the frequency range from 1 kHz to 500 kHz, preferably between 20 and 150 kHz.
a DC voltage signal can be superimposed on the setpoint signal which is proportional to the voltage across the controlled semiconductor switch 3.
This DC voltage signal can be positive or negative and change over times that are large compared to a period of the AC voltage source.
the level of the DC voltage signal can be set by appropriately dimensioning the resistors 15, 16 and 19.
the diodes 14 and 18 serve to decouple the DC voltage signal from the voltage of the voltage divider 10 and 11 respectively.
