ABSTRACT:
A power supply circuit in which the mains voltage which is applied across the primary winding (2) of a transformer (1) to generate a first direct voltage across a first capacitor (C.sub.1) by means of a secondary winding (3) and a first rectifier (D.sub.1) and a second direct voltage is generated across a second capacitor (C.sub.2) by means of a tertiary winding (4) and a second rectifier (D.sub.2). If the mains voltage is not connected, a first direct voltage is supplied by a battery (15) connected in parallel with the first capacitor (C.sub.1). The second direct voltage then is generated from the battery voltage of the battery (15) by means of an inverter circuit (20), a transistor (T.sub.1), the secondary winding (3) and the the tertiary winding (4).
