A magnetic circuit with several magnetic components integrated on one or more common magnetic cores utilises a power supply circuit which is familiar in itself. The circuit comprises a transformer, the ends of whose secondary winding are connected to like electrodes of a pair of rectifying diodes, whose other electrodes are connected to one output terminal of the power supply circuit. Furthermore, there are two reactive components, and the first electrodes of the diodes are connected to the other output terminal of the power supply circuit via one of the reactive components. The number of turns of the winding of the two mentioned reactive components is basically chosen equal to the number of turns of the secondary winding of the transformer. The two mentioned reactive components are arranged each on its own part of the core so that the resulting magnetic flux in the common core parts is approximately equal to the difference between the magnetic flux of the two core parts, and the secondary winding of the transformer is arranged on said common core parts. <IMAGE>
