Abstract
A converter receiving an A.C. voltage between an input terminal and a reference terminal and providing two D.C. voltages of opposite polarities across a first and a second capacitor. The converter includes a first switch connected the input terminal and a node of the circuit; a third capacitor, connected in parallel with the first capacitor, between the node and the reference terminal; circuitry including a second switch for connecting, in series, the second capacitor and the third capacitor when the second switch is closed; and a control circuit for closing the first switch only at the beginning and at the end of halfwaves of given polarity, the first switch being open when the second switch is closed.
