Abstract
A circuit including a dc/ac converter for supplying an ac consumer with an alternating voltage, such as a sinusoidal voltage, from a dc voltage source has an auxiliary load circuit which is connected in parallel with the ac consumer, the auxiliary load circuit being switched into the overall circuit by a controlled switching element. The control electrode of the controlled switching element is connected to the output of a voltage comparator, having inputs respectively supplied with an actual voltage derived from the voltage being used by the ac consumer and a theoretical signal derived from the output voltage of the dc/ac converter or from a reference oscillator which controls the converter. The controlled switching element becomes conductive when, as a result of the release of electrical or magnetic energy stored in reactive impedance components, the voltage used by the ac consumer exceeds an instantaneous value of the theoretical signal.
