Converter a subject matter a unipolar or bipolar has two windings magnetically pairs.

摘要

In order to reduce the cost of a switched-mode converter delivering a dc voltage across the terminals of a load (z), it is proposed, according to the present invention, a circuit with two windings (lp and ls) and a single magnetic core, which makes it possible to reduce the cost and size of the circuit. It is then necessary to add two diodes (d3, d4) to the circuit, but these elements are of low cost and small size.
