DC/DC converter with a transformer

摘要

The invention relates to a DC/DC converter with a transformer (2) whose secondary winding (4) is connected to a rectifier circuit (16, 18, 19, 20). The primary winding (3) of this transformer (2) is in this case supplied, via a centre tap (8), with a first potential (+U), while the end connections (9, 11) of this primary winding (3) can be connected via switching means (10, 12) to a second potential (OV) which is negative with respect to the first potential (+U). <IMAGE>
