The characteristics of present embodiment 1 are: accomplish the control of power switch triode failure of oscillation by relay J, realize the function conversion of energy-saving standby and complete machine operate as normal.To be button K manually touched logical or when presenting 1 or 0 by the current potential that remote signal changes the logic electrical output terminal, relay discharges or adhesive when corresponding status signal.So relay contact short circuit Or open circuitBase stage-the emitter-base bandgap grading of power switch triode ends or operate as normal corresponding power switch triode, thereby realizes the function conversion of energy-saving standby and complete machine operate as normal.Change its duty like need, all can realize with manual or remote control thereof.
The mentality of designing of present embodiment 1 is: when module input L, N connection 220V (50/60) HZ alternating current, the constant amplitude dc pulse width modulation voltage (PWM) that is transformed into the KHz order of magnitude through the modular power source basic circuit is given energy-storage capacitor C 0Charging.At this moment energy-storage capacitor C 0Be equivalent to a dynamic power supplies.Accept the charging of the constant amplitude direct current high-frequency pulsed width modulation voltage (PWM) of modular power source basic circuit output on the one hand, form (6-10) V DC voltage.On the other hand through circuit of three-terminal voltage-stabilizing integrated IC 3Still need the colour TV of work and the V of the CPU in the similar products complete machine when giving standby DDEnd provides the quiescent operation voltage and current of 5V * 0.04A=0.2W.Therefore, modular power source output power design maximum is 10V * 0.1A=1.0W, is enough to satisfy the requirement of various types to output power.Such design proposal is convenient to adopt magnetic integrated planar technology (SMT, MCM), helps the miniaturization of module, integrated, integrated, standardization.Will satisfy the requirement of relay starting to electric energy simultaneously, this depends on that storage capacitor choice of capacity and threshold voltage trigger the acting in conjunction of positive-feedback circuit.The storage capacitor choice of capacity can change the energy storage power of dynamic power supplies.The numerical value of threshold voltage is decided by the rated voltage of relay coil.When having only the charging voltage of electric capacity to reach the threshold voltage of design, by diode D 3, resistance R 3, stabilivolt DW 1The threshold voltage of forming triggers the condition that branch road just possesses conducting, thereby triggers by triode G 1With triode G 2And the threshold voltage of the TV module of peripheral cell composition triggers positive-feedback circuit 1001 entering quasi-operating status.The output state of relevant with it logical circuit is also depended in the conducting work (adhesive of relay) of TV module threshold voltage triggered positive-feedback circuit 1001.The input 5T (or 4T), the Q that just are decided by logical circuit bThe state of end.This only when the electric capacity sufficient voltage; The be allowed for access design of quasi-operating status of circuit; Both guaranteed that voltage and current (power) satisfied the requirement of relay J starting; Greatly reduce requirement again,, realize the energy-efficient and integrated condition of having created for reducing the module volume to the modular power source output power.
The principle of work of the modular power source basic circuit 12 of relay control switch power supply failure of oscillation mode is following:
When the alternating current of L, logical 220V (50-60) Hz of N termination, through rectifier bridge Q bBe transformed into corresponding dc pulse moving voltage, through switch transformer T bPrimary coil P 1With power switch pipe G bEmitter form oscillation circuit, at G bBase stage PulseTake place to reach Arteries and veinsUnder the instantaneous high level effect that wide automatic modulation circuit produces, current in loop is at switch transformer T bOne-level coil P 1Produce negative just down electromotive force on the winding, this moment is because switch transformer T bTwo utmost point winding P 2Induction electromotive force be last negative down just, high-frequency rectification diode D bEnd, then electric energy with the stored in form of magnetic energy at switch transformer T bInner.When excitation pulsewidth voltage is low level, power switch pipe G bEnd, flow through switch transformer T bOne-level coil P 1So the conducting current vanishes of winding is switch transformer T bOne-level coil P 1Winding produces through self-induction and is just going up negative electromotive force down, to stop the decline of electric current.This moment switch transformer T bSecondary coil P 2The pulse voltage of bearing just down on winding produces, this voltage is through diode D bRectification is to energy-storage capacitor C 0Charging powers to the load from A, the output of D end.Switching Power Supply come to this (high frequency) fast accomplish the energy conversion of electricity-magnetic-electricity.Because power switch pipe G bWork on off state: pressure drop is near zero during conducting, and electric current is zero when ending, so power consumption is very low, and efficient is very high, and volume is less.Under the energising situation, the modular power source basic circuit 12 that is applied to relay control switch power supply failure of oscillation mode can pass through short circuit NPN type or MOSEFT type power switch pipe G bBase-emitter or G, the S utmost point, power controlling switching tube G bFailure of oscillation, thus make power switch pipe G bNo-output, no power consumption.Otherwise, cancellation short circuit, power switch pipe G bRecover normal operating conditions.Power switch pipe G bBase-emitter-base bandgap grading or G, the S utmost point, be connected to the conversion contact J of relay J respectively 2And normally opened contact J 2-2, can be to power power switch pipe G bBase-emitter-base bandgap grading carry out short circuit or the cancellation short circuit operation.In like manner, relay conversion contact J 1And normally closed contact J 1-1Can be to power power switch pipe G aBase, emitter-base bandgap grading carry out short circuit or the cancellation short circuit operation.
The principle of work of TV module threshold voltage triggered positive-feedback circuit 1001 is following:
The voltage of holding as A meets or exceeds by diode D 3, resistance R 3With stabilivolt DW 1When the threshold voltage of forming triggered the threshold value of branch road, this branch road possessed turn-on condition, but because triode G 1With triode G 15Connection be serial arrangement, therefore, triode G 1Break-make also be decided by triode G 15Break-make.Triode G 15The E end is electronegative potential (0), triode G during conducting 15The E end is noble potential when ending.The method is called for short the series connection control method.The TV module all adopts the series connection control method: be applied to TV module biconditional gate and with the triode G of rejection gate logical circuit 51 when being controlled by 15During conducting, the threshold voltage that has possessed turn-on condition triggers branch road and triode G 1Base-emitter-base bandgap grading and triode G 15Collection-penetrate level just can form path, so following positive feedback process takes place: triode G 1Conducting → triode G 2Biasing resistance R2 branch road can produce bias current → triode G 2Conducting → triode G 1Go up inclined to one side resistance R 1Can produce bias current → triode G 1Conducting.At this moment energy-storage capacitor G 0The electric energy that stores is through relay coil J, triode G 1And G 15So the discharge of collection-emitter-base bandgap grading loop is relay J starting adhesive.Relay J after the adhesive has from TV primary power dc low-voltage, through diode D 2Power supply is so relay J is in hold mode.
Integrated regulator IC 3Use LM7805 or 78L05 type integrated circuit, its effect is stable WV and electric current to module electronic circuit and CPU to be provided.
The principle of work that is used for TV module triggering upset logical circuit 41 is following:
The A terminal voltage is through the three-terminal voltage-stabilizing IC circuit 3Be transformed into the rated operational voltage V of CPU in the machine DD, and as the double D trigger IC 4WV.The double D trigger IC 4Can constitute by CD4013 type integrated circuit or two 74H74 integrated circuit.Switch on moment, because capacitor C 2The differential action, D bThe reset terminal R of trigger bBe noble potential, simultaneously because set end S bBe electronegative potential, so the forward output terminal Q of Db trigger bBe reset electronegative potential, inverse output terminal (Q bInstead) be noble potential, be Q bUpset is ready next time.The Da trigger is switched on moment, because set end Sa and reset terminal R aBe all electronegative potential, therefore export Q aEnd is random state, and at this moment it is to D bTrigger Q bOutput do not exert an influence.If Q aBe electronegative potential, when button K makes 8T, D end short circuit → triode G 9Base stage, emitter short circuit → G 9By → set end S aNoble potential → triode G 8Conducting → reset terminal R aSo electronegative potential is D aTrigger is set into noble potential Q a=1; Work as Q aWhen electronegative potential jumps to noble potential, through D bThe positive pulse of trigger triggers input end CP b, make Q bBe turned to high potential state from electronegative potential.It may be noted that Q aAfter jumping to noble potential from electronegative potential, can automatically reset to low-potential state again at once, this be because: after the conducting of button K manual triggers, disconnection → triode G immediately 9Conducting → set end S aGround connection → triode G 8By → Q aEnd output+5V passes through R 12To capacitor C 1Charging → reset terminal R aBecome high level → Q aEnd resets to low level again, for positive pulse generation is next time got ready.So, be used for TV module triggering upset logical circuit 41 and have following function: during energising, Q bEnd is reset and holds R bReset to electronegative potential, whenever click button K, Q afterwards bJust upset once.Q bEnd can be used as and is used for TV module biconditional gate and with 51 1 manual input signal ends of rejection gate logical circuit, thereby changes the duty of complete machine, makes whole TV start or shutdown.

The power source for relay control failure of oscillation mode modular circuit 91 that is applied to PC is following in the application course of work of PC complete machine:
When the logical 220V of PC complete machine AC termination, 50HZ power supply, the L of PC module, the N end is connected the 220V power supply simultaneously.If this moment, the PC main frame was provided with under the state usually, the logic state signal 9P end of module is 0 current potential → analog switch S 2The control utmost point 805 ends 0 current potential → analog switch S 2803 and 804 ends by → analog switch S 48010 and 8011 end break-makes by time-delay analog switch S 3808 and 809 ends, triode G 12Penetrate-collect the utmost point, resistance R 24The break-make decision of branch road (being called for short " branch road ").S 48010 and 8011 end break-makes affect triode G simultaneously 1Break-make, the method abbreviates the Parallel Control mode as, the PC module all adopts the Parallel Control mode.Manually start shooting moment, because resistance R 22, capacitor C 5The time-lag action of integrating circuit, S 3The control utmost point 806 ends

short circuit PC host power switch line → mainboard electronic switching tube conducting once → ATX primary power work of 801 and 802 instantaneous conducting → PC modules, thereby make complete machine get into normal operating conditions.Simultaneously because the conversion contact J of relay J 2With its normally opened contact J 2-2Closure, short circuit be applied to the switch triode G in the modular power source basic circuit 12 of relay control switch power supply failure of oscillation mode bBase, emitter-base bandgap grading or G, the S utmost point, make the modular power source failure of oscillation and do not work.After software shutdown, be provided with usually under the state, not only the ATX primary power is not worked, and the ATX accessory power supply do not work yet, so idling consumption is very little.Under the state that is arranged on mouse, keyboard, network open and close machine function, after the software shutdown, have only the ATX primary power to quit work, the ATX accessory power supply is still in work, and this is as not adding module ATX power supply before.

8011 end break-makes by delay switch S 3808 and 809 ends, triode G 12The e-c utmost point, resistance R 24The break-make decision of branch road (being called for short " branch road ").(S 4Break-make affect triode G simultaneously 1Break-make, the method abbreviates the Parallel Control mode as, the PC module all adopts the Parallel Control mode).Manually before the start, be applied to triode G in the logic control circuit 61 of PC 10, G 11Hold electronegative potential → D by → H 3, R 3, DW 1Branch road ends → G 1By → R A2, DW 3, G xBase-penetrate branch road and have bias current to pass through → switch triode G xConducting → photo-coupler IC aConducting → ATX accessory power supply switch triode G aBase, emitter-base bandgap grading do not worked by short circuit → ATX accessory
