Abstract
In an AC/DC converter including an autotransformer having a primary winding connected to an AC power supply network and two secondary windings connected to two rectifier circuits operating in parallel to deliver a DC voltage to a load, the two same-polarity outputs of the two rectifier circuits being connected to respective first ends of a first coil and of a second coil whose second ends are connected together to form a first output of the converter, and the two outputs of the two rectifier circuits having the same other polarity being connected respectively to the first ends of a third coil and of a fourth coil whose second ends are connected together to form a second output of the converter, provision is made for the first, second, third, and fourth coils are wound on a common magnetic core. The invention is applicable to converters for use on board aircraft.
