Abstract
A switched mode power supply is provided that has two output circuits one of which is directly regulated by control of the input switching device and the other of which is indirectly regulated. This indirect regulation is provided by means of an additional winding wound in common on an energy-storing magnetic core with windings of the first and second output circuits. The additional winding is connected between a lower-voltage one of the output circuits and the other, higher-voltage, output circuit such that when the lower-voltage output circuit is lightly loaded current can flow from this output circuit through the additional winding to the higher-voltage output circuit, this current decreasing as the loading on the lower-voltage output circuit increases.
