Embodiment
A kind of low-power consumption dual power supply energy-saving circuit as shown in Figure 1 comprises capacitor step-down power supply circuits and controlled feedback circuit; Through said controlled feedback circuit control output voltage.
Said capacitor step-down power supply circuits comprise discharge resistance R1, decompression capacitor C1, half-wave power supply diode D1, discharge diode D2,12V voltage-stabiliser tube D3 and filter capacitor C3.L, N are that circuit provides 220V alternating current, after the power failure, bleed off the electric weight at decompression capacitor C1 two ends through discharge resistance R1, prevent that high pressure from hurting sb.'s feelings.
Said controlled feedback circuit comprises current-limiting resistance R4, voltage stabilizing didoe D4, the first triode Q1, the second triode Q2, the 3rd resistance R 3, the 5th resistance R 5,101 control chip and relay J; Said 101 control chips are connected the output voltage two ends, are used to produce the Opportunity awaiting control for linear signal, control the first triode Q1 conducting and end; The said first triode Q1 base stage is electrically connected with said 101 control chips through the 3rd resistance R 3, and emitter connects AC power N line, and collector electrode is connected to the positive terminal of output voltage via relay J; The said second triode Q2 base stage is connected to being connected in series of said relay J and the said first triode Q1 collector electrode through the 5th resistance R 5, and emitter connects AC power N line, and collector electrode is connected to the positive terminal of output voltage via voltage stabilizing didoe D4, current-limiting resistance R4.
Voltage-stabiliser tube D3 forms the galvanic current source with filter capacitor C3, and this power supply is 101 control chips, and relay J provides operating current.101 control chips are controlled shutoff or the conducting of the first triode Q1 through R3 resistance.In normal operation: the first triode Q1 conducting, the relay J adhesive, the second triode Q2 turn-offs.At this moment, filter capacitor C3 two ends are stable 12V direct voltage.Under holding state, the first triode Q1 turn-offs: relay J dead electricity and turn-offing, the positive terminal of output power supply circuit output voltage is through the microampere order current trigger Q2 conducting of R4.D4 is the 5.1V voltage stabilizing didoe, and this moment, filter capacitor C3 voltage was reduced to 5.4V (voltage stabilizing didoe D4 voltage adds the 0.3V pipe pressure of Q2).R4 is the current-limiting resistance in 24 Europe, prevents that big electric current from burning out D4.Supply voltage drops at 5.4 o'clock from 12V, and the electric current I that flows through half-wave power supply diode D1 changes little.But power consumption has dropped to 5.4 * I from 12 * I.So just realized low-power consumption standby cheaply.
