Schaltungsvorrichtung zur annähernd sinusförmigen Absenkung einer Wechselspannung

摘要

The invention relates to a circuit device for quasi-sinusoidal lowering of an AC voltage, which is composed of a voltage divider transformer with at least one tap, whose low end is connected to the neutral wire via a first switch and whose winding or part of said winding can be magnetically short-circuited via a second switch, whereby said two switches can be alternately turned on and off at the AC voltage frequency.
