Description

A kind of stand-by energy-saving stabilizing circuit of television set
Technical field:
The present invention relates to a kind of used as television electronic circuit.
Background technology:
When existing a lot of TV set power entered holding state, its operating voltage did not all have to change, like this, during standby the consumption of electric energy bigger, reach more than the 9W, like this, consume electric power not only, and high voltage also can influence the life-span of electronic component.If reach below the 9W, then must increase complicated control circuit, cause product cost to rise, the power of striving unexpectedly descends.
Summary of the invention:
Invention of the present invention be to provide a kind of standby power consumption less, be not easy to influence the stand-by energy-saving stabilizing circuit of the extremely low television set of electronic component useful life and cost.
The present invention realizes like this, comprise by self-oscillating switch circuit, sample circuit, comparison circuit, voltage stabilizing circuit and standby switch circuit that variable resistor R1 constitutes, self-oscillating switch circuit by resistance respectively with variable resistor R1, sample circuit links to each other, comparison circuit respectively with self-oscillating switch circuit, sample circuit links to each other, its special feature is to be provided with a regulating circuit between the sampling point of the sample circuit of voltage stabilizing circuit and standby switch circuit, regulating circuit is mainly by resistance R 2, diode D1, capacitor C constitutes, resistance R 2, be serially connected between the sampling point and standby switch circuit of voltage stabilizing circuit capacitor C and resistance R 2 after the diode D1 series connection, diode D1 also connects back ground connection.During work, when television set is in normal operating conditions, triode conducting in the standby switch circuit, resistance R 2 is in parallel with resistance R 1, resistance reduces after the two resistance parallel connections, by regulating variable resistor R1, makes the voltage of sampling point corresponding with the normal operating voltage of television set, like this, under self-oscillating switch circuit, sample circuit, comparison circuit control stable operating voltage on the normal operational voltage value of television set; When television set is in holding state, triode in the standby switch circuit disconnects, the A point voltage raises, corresponding output services voltage decreases, like this, stable operating voltage is being lower than the normal operational voltage value of television set under self-oscillating switch circuit, sample circuit, comparison circuit control, makes Switching Power Supply be in intermittently concussion state, thereby has reduced the power consumption of television set holding state.Capacitor C plays the effect of filtering, with prevent control circuit open/when opening circuit to the influence of voltage stabilizing circuit.
The present invention is owing to adopted between the sampling point of voltage stabilizing circuit and standby switch circuit one regulating circuit has been set, reduce the power consumption of television set standby by the mode that reduces operating voltage, therefore, have simple and reliable for structure, manufacturing cost is extremely low, can reduce standby energy consumption effectively, be not easy to influence the electronic component advantage in useful life.
Description of drawings:
Fig. 1 is a circuit diagram of the present invention.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention includes by self-oscillating switch circuit, sample circuit, comparison circuit, voltage stabilizing circuit and standby switch circuit that variable resistor R1 constitutes, self-oscillating switch circuit by resistance respectively with variable resistor R1, sample circuit links to each other, comparison circuit respectively with self-oscillating switch circuit, sample circuit links to each other, between sampling point A that its special feature is at the sample circuit of voltage stabilizing circuit and standby switch circuit one regulating circuit is set, regulating circuit is mainly by resistance R 2, diode D1, capacitor C constitutes, resistance R 2, be serially connected between the sampling point and standby switch circuit of voltage stabilizing circuit capacitor C and resistance R 2 after the diode D1 series connection, diode D1 also connects back ground connection.
