The operation principle of standby power management circuit of the present invention is described in detail below：
As shown in Fig. 2 accessing 220V AC powers by power interface 10,220V AC powers pass through the first electric capacity all the way
C1 and the second electric capacity C2 isolation is depressured, and is coupled to the first diode D1, the second diode D2, the 3rd diode D3 and the
Four diode D4 carry out full-wave rectification, and the DC current after rectification slowly charges to the 3rd electric capacity C3, the 3rd electric capacity C3 two ends
Voltage is slowly raised, after voltage is increased to 5.1V, because the voltage stabilizing two that voltage stabilizing value is 5.1V has been accessed at the 3rd electric capacity C3 two ends
Pole pipe D5, the voltage stabilization at the 3rd electric capacity C3 two ends is in 5.1V, it is ensured that the 3rd electric capacity C3 two ends maximum voltages not over 5.1V,
So as to which the first DC voltage that step-down rectifier module 20 is depressured to 220V AC powers and exported after rectification processing is in theory
For 5.1V.
Electronic apparatus is under open state, and the first DC voltage and power module 70 that step-down rectifier module 20 is exported are exported
The second DC voltage by the 5th diode D6 in power supply composite module 30, the 6th diode D7 carry out it is compound after export the
Four DC voltages (such as 5V), by the 4th DC voltage to light controllable silicon 40, trigger unit for thyristor 60 and IR signal reception
Device IR1 powers.Here, when power module 70 connects AC power, the second DC voltage is 5V, when the access failure of power module 70
The second DC voltage is 0V during AC power.
The 4th DC voltage that power supply composite module 30 is exported is all the way by first resistor after the 4th electric capacity C4 filtering
R1 is input to infrared signal receiver IR1 power pins, is powered to infrared signal receiver IR1；4th DC voltage is another
Road is input to the anode of the light emitting diode inside light controllable silicon 40, and the 4th another road of DC voltage is charged to the 6th electric capacity C6,
Now triode Q1 base stage is in low level state, triode Q1 conductings so that the light emitting diode inside light controllable silicon 40
Luminous, so that light controllable silicon 40 is turned on, now the connection of power module 70 AC power, i.e. 220V AC powers passes through light controllable silicon
Controlling switch inside 40 is linked into power module 70, and power module 70 exports the second DC voltage+5V after connecting AC power
With load (such as master controller 80) power supply of the 3rd DC voltage+VCC (such as+3.3V) electron electrical equipment.
Under open state, when infrared signal receiver IR1 receives infrared signal, infrared signal receiver IR1's is defeated
The output signal for going out pin becomes pulse signal IR_OUT from high level, and the pulse signal is by the 7th diode D8 to the 6th electricity
Hold C6 chargings, meanwhile, the output of pulse signal to master controller 80 opens standby test side.Master controller 80 is believed according to the pulse
Number judge whether the infrared signal that infrared signal receiver IR1 is received is standby signal.When master controller 80 identifies infrared letter
When number being not standby signal, control electronic apparatus maintains open state.When master controller 80 identifies that infrared signal is standby letter
Number when, master controller 80 exports the control signal STANDY_BY of high level by its signal output part, i.e. off signal, now
9th diode D10 ends, because the voltage at the 6th electric capacity C6 two ends is raised so that triode Q1 base stage is changed into high level shape
State, triode Q1 cut-offs, so that light controllable silicon 40 ends, the AC power of deenergization module 70 is powered, and electronic apparatus enters
Holding state.
Or, under open state, when button 90 is pressed, the standby test side of opening of master controller 80 is pulled to low electricity
It is flat, that is, detect that signal POWER_ON is changed into low level, it is button off signal that master controller 80, which recognizes now detection signal, main
Controller 80 sends the control signal STANDY_BY of high level, i.e. off signal, now, the 6th electric capacity C6 electric discharges so that three poles
Pipe Q1 base stage is changed into high level, and triode Q1 switchs to cut-off state by conducting state, so that light controllable silicon 40 ends, disconnects electricity
The Alternating Current Power Supply of source module 70 so that electrical equipment enters holding state.
Electronic apparatus in the standby state, when infrared signal receiver IR1 receives infrared signal, infrared signal receiver
The output signal of IR1 output pin becomes pulse signal from high level, and the pulse signal gives the 6th by the 7th diode D8
Electric capacity C6 charges, meanwhile, the output of pulse signal to master controller 80 opens standby test side.Master controller 80 is according to the pulse
Signal judges whether the infrared signal that infrared signal receiver IR1 is received is starting-up signal, when master controller 80 identify it is infrared
When signal is not starting-up signal, control electronic apparatus maintains holding state.When master controller 80 identifies that infrared signal is standby
During signal, master controller 80 exports low level control signal STANDY_BY, i.e. starting-up signal by its signal output part, this
When the 9th diode D10 turn on so that triode Q1 base stage is changed into low level state from high level, triode Q1 conductings, enters
And light controllable silicon 40 is turned on, the AC power of the module that switches on power 70 is powered, and electronic apparatus enters open state.
Or, in the standby state, when button 90 is pressed, the standby test side of opening of master controller 80 is pulled to low electricity
It is flat, that is, detect that signal POWER_ON is changed into low level, while triode Q1 base stage is also pulled to low level, triode Q1 is led
Logical, so that light controllable silicon 40 is turned on, power module 70 exports the second DC voltage+5V and the 3rd DC voltage+VCC to main control
Device 80 is powered, and it is button starting-up signal that master controller 80, which recognizes now detection signal POWER_ON, and master controller 80 sends low
The control signal STANDY_BY of level, that is, send starting-up signal, and now triode Q1 base stage turns on for low level, and then
Light controllable silicon 40 is turned on, and power module 70 has AC power to power always, and electronic apparatus enters open state.
In summary, due under holding state, only the first electric capacity C1, two high-voltage safety ceramic electricals of the second electric capacity C2
Hold, and the rectifier bridge being made up of the first diode D1, the second diode D2, the 3rd diode D3 and the 4th diode D4 is long-term
Power supply, step-down rectifier module 20 AC power is depressured and rectification after the first DC voltage for exporting by power supply compound die
Block 30 is powered to IR signal reception module 50, trigger unit for thyristor 60 and light controllable silicon 40, due to light controllable silicon 40 and can
Control the triode Q1 in silicon trigger module 60 and be in cut-off state in the standby state, triode Q1 and light controllable silicon 40 are without electricity
Stream is consumed, and the AC power of already off power module 70 is powered, and AC power does not export the second DC voltage and the 3rd
DC voltage, AC power and master controller 80 also without current drain, only infrared signal receiver IR1 consume 0.5mA with
Under electric current, now infrared signal receiver IR1 consumption power P=5.1V*0.5mA=2.505mW, close to zero-power.
