Abstract
A circuit for converting an input d.c. voltage into a stabilized output d.c. voltage. The circuit comprises a plurality of supply networks having diodes which are arranged in series and have the same conductivity direction, and the series network of an inductor and a storage capacitor in parallel with one of the diodes. The series diodes of a supply network are arranged in parallel with the storage capacitor of a supply network located closer to the input voltage source, the diode of the first supply network being connected to said source. A winding is connected by means of one side to the junction between the inductor and the capacitor of the supply network located remote from the source and by means of its other side to a further diode and to a controllable switch, the other side of the further diode being connected to the junction between the first and the second diode of the network located remote from the source. The circuit comprises also a tuning capacitor. The output voltage is kept constant by control of the period of time during which the switch is conducting.
