It is described a circuit for regulating a DC voltage, the circuit comprising: a controllable switch system (102, 202, 302) having a first terminal (101), a second terminal (105), a first control terminal (107), and a second control terminal (207), wherein the controllable switch system is adapted to establish an electrical connection between the first terminal and the second terminal, if a first control signal applied to the first control terminal satisfies a first criterion or if a second control signal applied to the second control termi-nal satisfies a second criterion; a resistor (104); a first control circuit (106); and a second control circuit (108). Further a method for regulating a DC voltage and an AC-to-AC--converter is described. |
