Abstract
A switched mode power supply having a first circuit provided with a primary winding of a transformer to which a pulse voltage is applied, a second circuit having a secondary winding of the transformer, a reactor provided with a magnetic core and which has a terminal connected to a terminal of the secondary winding, at least one filter provided with input and output terminals and a first diode connected in parallel to the input terminals of the filter is shown. The other terminal of the reactor is connected to a terminal of the first diode. The power supply includes a second diode that has a first terminal connected to the other terminal of the first diode and a second terminal connected to the other terminal of the secondary winding and a control circuit coupled to an output terminal of the filter and to the other terminal of the secondary winding. The control circuit generates a current able to reset the magnetic core of the reactor.
