Abstract

In a device for converting an alternating voltage (V) to a DC-voltage and including a rectifier bridge (D1) and a converter (P2), two series circuits are coupled in parallel across the input of the converter (P2). One of these series circuits includes a first capacitor (C1) and a first diode (D2), and the other of the circuits includes a second diode (D3) and a controlled switch (T). A coil (L1) is coupled between the connection node (10) between the first capacitor (C1) and the first diode (D2) in the one series circuit, and between the connection node between the second diode (D3) and the controlled switch (T) in the other series circuit. One output terminal of the rectifier bridge (D1) is connected to the connecting node between the first diode (D2) and the controlled switch (T), while the other output terminal of the rectifier bridge (D1) is connected to a switch (SW1) which functions to connect selectively the second connecting terminal to the connection node (12) between the first capacitor (C1) and the second diode (D3), or alternatively to the connection node (10) between the first capacitor (C1) and the first diode (D2).
