Voltage converter
First Claim
1. A voltage converter of a flux converter type having a self-regulating synchronous rectifier in the secondary circuit related to a transformer (17),characterized in that a capacitor device (C1;
- C1, C2) is provided for driving an active switching element (V1, V2) of the synchronous rectifier, which is charged by means of an auxiliary winding (W1, W2) of the transformer in the secondary circuit, and its charge is applied to a control terminal of the active switching element by means of a semiconductor element (D1, D2;
30, 32), with the capacitor device being implemented in such a way that the charge allows synchronous switching operation of the active switching element.

Abstract
The invention concerns a voltage converter of a flux converter type with a self-regulating synchronous rectifier in the secondary circuit related to a transformer (17), with a capacitor device (C1; C1, C2) being provided, for driving an active switching element (V1, V2) of the synchronous rectifier, which is charged by means of an auxiliary winding (W1, W2) of the transformer in the secondary circuit, and its charge is applied to a control terminal of the active switching element by means of a semiconductor element (D1, D2; 30, 32), with the capacitor device being implemented in such a way that the charge allows synchronous switching operation of the active switching element.
