Abstract:
1. A stabilization circuit for compensating voltage fluctuations at a user device containing device circuitry supplied with a mains voltage available across mains voltage poles, said device circuitry having two inputs and exhibiting a load voltage, said stabilization circuit comprising: a transformer having a primary winding and a secondary winding; a switched power pack having an input and two outputs; said primary winding of said transformer being adapted for connection across said mains voltage poles, and said secondary winding being connected to said input of said switched power pack; one of the outputs of said switched power pack being adapted for connection to one of said mains voltage poles; another of said outputs of said switched power pack being adapted for connection to said one of said inputs of said device circuitry; a connection line adapted to connect another of the inputs of said device circuitry to another of said mains voltage poles; said outputs of said switched power pack supplying, upon occurrence of a fluctuation in at least one of said mains voltage and said load voltage, a voltage to said device circuitry, in series with said mains voltage; and said switched power pack having another input connected to said secondary winding of said transformer and, in said switched power pack, said another input connected to said secondary winding of said transformer being connected to said output adapted for connection to said another of said mains voltage poles, and said switched power pack, dependent on said fluctuation, selectively connecting said output adapted for connection to the device circuitry to said output adapted for connection to said one of said mains voltage poles or to said another input of said switched power pack connected to said secondary winding of said transformer.
