Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments to the utility model further instruction.
Embodiment: see Fig. 1.
A power circuit for super-low standby power consumption, comprises start-up circuit, operating circuit and readiness control circuit, start-up circuit is connected with operating circuit and readiness control circuit respectively, also comprise standby switch circuit, operating circuit is connected with start-up circuit signal respectively by standby switch circuit with readiness control circuit, when power supply normally works, readiness control circuit sends a low level signal to standby switch circuit, on-off circuit is in channel status, start-up circuit controls operating circuit work by standby switch circuit, when power supply is in standby, readiness control circuit sends a high level signal to standby switch circuit, standby switch circuit is in off state, operating circuit quits work.
In the technical program, start-up circuit, operating circuit and readiness control circuit can be all available circuit, and due in available circuit, when PC is in standby, the operating circuit part in power supply is still in running order, thus causes power supply power consumption larger; In the technical program, controlling the duty of operating circuit by arranging standby switch circuit, when standby, the electric current of operating circuit can be cut off completely, reduce power consumption.
Further, described standby switch circuit comprises triode Q3 and triode Q2, the base stage of triode Q2 is connected with readiness control circuit, the grounded emitter of triode Q2, triode Q2 collector be connected with the base stage of triode Q3, the collector of triode Q3 is by electric capacity C11 ground connection, and the collector of triode Q3 is connected with start-up circuit, the emitter of triode Q3 is connected with operating circuit, and the base stage of triode Q3 is connected with the collector of triode Q3 by resistance R9.As dotted portion in Fig. 1.
Due to readiness control circuit in working order time, feedback be low level, time standby feedback be high level; Therefore need to select suitable standby switch circuit, this standby switch circuit in working order time, triode Q2 ends, the base stage of triode Q3 is substantially identical with the voltage of collector, remain on high level state, triode Q3 conducting, the control electric current of start-up circuit flows to operating circuit by the collector of triode Q3, emitter, controls operating circuit work.When standby, readiness control circuit sends high level signal to the base stage of triode Q2, and triode Q2 conducting, make the base stage of triode Q3 by triode Q2 ground connection, triode Q3 ends.As shown in Figure 1, time standby, the PS-ON pin of U3 exports high level, Q2 conducting, and Q3 ends.The VCC voltage that T3 exports through D10 rectification is cut off, and the power supply of the T2 transformer of supply major loop is cut off, and T2 transformer is without supply voltage, and major loop, without any line work, can reduce power consumption.When normally working, the PS-ON pin output low level of U3, Q2 ends, Q3 conducting.The VCC voltage supply T2 of T3 after D10 rectification, major loop normally works.
Further, start-up circuit comprises chip U3, and chip model is: 8107B, and the OB pin of chip U3 is connected with power firestreak by resistance R10, and the OC pin of chip U3 is connected with standby switch circuit by transformer T3.
Adopt this IC of 8107B, its inside is integrated with the high-voltage power MOSFET of a PWM PDM keyer and a 600-700VV.Starting current is very low, and current mode pulse width modulation makes to be operated in energy saver mode when underloading.Reduce the frequency of operation of circuit, Loss reducing.The utility model has been done to explain, and those of ordinary skill in the art should be appreciated that and can modify to the technical solution of the utility model or equivalent replacement, and does not depart from essence and the scope of technical solutions of the utility model.
