AbstractA power supply apparatus for the television receiver set comprising a television receiving circuit and other receiving circuits, for example, satellite broadcasting receiving circuit or character broadcasting receiving circuit, each of receiving circuit is supplied with a supply power from the same switching power supply of regenerative type having plural secondary windings wherein some receivers are selectively turned off by switches provided the receivers and the switching power supply for automatic recording or standby mode. The regenerative type of switching power supply has a stable output characteristic over a range from no load to the maximum load because of regenerative operation. The horizontal scanning circuit is turned off by the switch. This causes the horizontal scanning circuit and vertical scanning and video signal processing circuits to stop operation because supply power of the vertical scanning and video processing circuits are supplied with power from tile horizontal scanning circuit through a high voltage generation circuit. The television having satellite broadcasting circuit and such power supply apparatus is also disclosed.
