Power supply apparatus for television receiver set and television receiver set including the same

A power supply apparatus for a television receiver set including a television circuit means and broadcasting receiving circuit means for receiving broadcast programs whose type is different from that of said television circuit means, comprising:

• (a) a regenerative type of switching power supply having a primary circuit for receiving an input supply voltage and a plurality of secondary circuits for respectively producing a plurality of supply voltages whose intensities are different from each other;
• and
• (b) switch means for controlling of supplying of a first supply voltage out of said plurality of supply voltages to said television circuit means in response to a control signal,
• wherein said broadcasting receiving circuit means comprises satellite broadcasting receiving means and a second supply voltage out of said supply voltages is supplied to said satellite broadcasting receiving means.

A power supply apparatus for a television receiver set including a television circuit means and broadcasting receiving circuit means for receiving broadcasting whose type is different from that of said television circuit means, comprising:

• (a) a regenerative type of switching power supply having a primary circuit and a plurality of secondary circuits for producing a plurality of supply voltages from an input DC supply, said plurality of supply voltages having different intensities, said primary circuit and one of said plurality of secondary circuits including regenerative means for returning a portion of a power received from said input DC supply to said input DC supply in accordance with a load of said one of said plurality of secondary circuits;
• and
• (b) switch means for controlling of supplying of a first supply voltage out of said supply voltages to said television circuit means in response to a control signal,
• wherein said broadcasting receiving circuit means comprises satellite broadcasting receiving means and a second supply voltage out of said supply voltages is supplied to said satellite broadcasting receiving means.

A television receiver set comprising:

• television circuit means for controlling video outputs of the television set;
• broadcasting receiving means for controlling reception of satellite broadcasting transmissions;
• a switching power supply of a regenerative type for receiving an input power and producing a plurality of supply voltages having different voltages in order to provide a first supply voltage to said television circuit means and a second supply voltage to said broadcasting receiving means;
• a control means for outputting a plurality of control signals to control said plurality of supply voltages being supplied to at least said television circuit means;
• and
• a first switch provided between said switching power supply and said television circuit means, said first switch allowing said first supply voltage of said switching power supply to be supplied to said television circuit means in response to one of said plurality of control signals from said control means.
