Control circuit for keeping the working voltage of an electricity consumer at a constant level

摘要

Subject of the present invention is for the electrical betreibbaren consumer (1) of konstanthalten regelungsschaltung voltage different voltages, in a phasenanschnittsteuerbaren series electronic switch circuit (2). And be by a referenzelement(4 in consumer (1) supply voltage value) (3) offer is compared by a vergleichselement design value, this connect with the electronic switch (2) of steueranschlu phasenanschnittsteuerbaren. It is that consumer (1) supply voltage value can combine or the formation adjacent from the voltage (2) on different average voltage and average phasenanschnittsteuerbaren electronic switches in finishing. The present invention is applied in household electrical appliance, k rperpflegeger ten.
