It addition, the primary side 7 of transducer is connected power input 4, it is Specifically connect with diode 5 and in parallel with commutation condenser 6.This transducer is constituted with transformator 8 form at this.The primary side 7 (such as primary coil) of transformator 8 is connected with the power elements in Switching Power Supply part 9 form again.The power supply outfan 12 of Switching Power Supply part 9 and being just connected for electric connection terminal VDD of the second control device being the microcontroller form being formed with MOS circuit, this microcontroller is referred to below as master controller 13.Master controller 13 is corresponding to above-mentioned " second control device ".That is, master controller 13 is powered by Switching Power Supply part 9.The signal output part 14 of master controller 13 is connected with the input of the first photoelectrical coupler 15.The signal input part 16 of master controller 13 is connected with the outfan of the second photoelectrical coupler 17.
The second circuit part 3 of circuit 1 has the primary side 18 of transformator 8 for its electric current supply or voltage supply.Primary side 18 is connected with the diode 19 that can play direction rectifier effect.Diode 19 is connected with first terminals of its anode connection end with the primary side 18 of transformator 8 at this and is connected with the first terminals 20 of electrical switch 21 with its cathode connection end.Switch 21 is constituted with stable crystal form of tubes of connecting at this.Second terminals 22 of switch 21 are connected for electric connection terminal 23 with the first of power elements 24.The second of power elements 24 is connected with the second terminals of the primary side 18 of transformator 8 for electric connection terminal 25.That is, power elements 24 is connected with switch 21.Therefore, it can the connection selectively set up by switch 21 and disconnect between its first terminals 20 and its second terminals 22, be Specifically the control input 26 by suitably controlling this switch 21.That is, by controlling or enable described switch 21, the primary side 18 of power elements 24 and transformator 8 and and then partition of powering with it open.
The power supply outfan 27 of power elements 24 controls just being connected of device for electric connection terminal VDD with the be another microcontroller form being formed with MOS circuit the 3rd.This microcontroller is referred to below as " satellite controller " 28 and corresponding to above-mentioned " the 3rd controls device ".Satellite controller 28 such as can serve as measuring and controlling or one part.The negative terminals VSS of satellite controller 28 and the second terminals of the primary side 18 of transformator 8 and and then be connected for electric connection terminal 25 with the second of power elements 24.Power elements 24 and satellite controller 28 collectively form the third circuit portion 10 being placed in second circuit part 3.
Satellite controller 28 has multiple input/output terminal (I/O port), i.e. the first signal output part 29, secondary signal input 30 and the 3rd signal output part 31.First signal output part 29 is connected with the input of the second photoelectrical coupler 17, and secondary signal input 30 is connected with the outfan of the first photoelectronic coupler 15.Thus, the first signal output part 29 of satellite controller 28 is connected with the signal input part 16 of master controller 13 by the second photoelectrical coupler 17, is Specifically isolate electric current by the second photoelectrical coupler 17 to be connected.Similarly, the secondary signal input 30 of satellite controller 28 is connected with the signal output part 14 of master controller 13 by the first photoelectrical coupler 15.The data of the isolation electric current being derived from master controller 13 and satellite controller 28 couple.They therefore can two-way mutual exchange data signals.
It addition, the outfan of the first photoelectrical coupler 15 is connected with another input controlling device of second circuit part 3 or wiring is connected.This control device is corresponding to above-mentioned " first control device " and referred to below as self-contained unit 35.The control output end 36 of self-contained unit 35 is connected with the control input 26 of switch 21.Therefore, master controller 13 property of can select that enables and disables self-contained unit 35, and self-contained unit is corresponding this switch 21 of start again, thus can selectively set up the electric current supply with deenergization part 24 or voltage supply.Therefore, can enable and disable the electric current supply of third circuit portion 10 by master controller 13 or voltage supply drives in other words.
That is, being followed by branch 32 at the outfan of the first photoelectrical coupler 15, it is forked to the secondary signal input 30 of satellite controller 28 on the one hand, is forked to the input of self-contained unit 35 on the other hand.That is, the signal output part 14 of master controller 13 data signal sent comes the secondary signal input 30 of satellite controller 28 and the input of self-contained unit 35 through the first photoelectrical coupler 15.

Self-contained unit 35 is so constituted, its starting switch 21 after receiving control signal (Tathagata autonomous controller 13 or the first photoelectrical coupler 15 or from satellite controller 28) reaches regulation and controls oneself the time, therefore sets up the power supply to power elements 24 in this self-holding time.This such as can by send in control output end 36 triggering signal complete.Wherein, this self-holding time especially can be longer than the minimum length in time of control signal.Self-contained unit 35 such as can have electric storage means such as capacitor for this, the electric energy of the control signal that its savings receive.That is, in order to switch 21 enable for a long time, self-contained unit 35 receives a succession of control signal just, the interval of this control signal not up to or not less than the self-holding time.
Home appliances H is generally connected to power input 4 for a long time after being placed in user place.On power input 4 general added with ac voltage signal, its by diode 5 and commutation condenser 6 be converted into through over commutation but still the d. c. voltage signal of tool waveform.This d. c. voltage signal is fed into the primary side 7 of transformator 8 and thus produces to be sensed by primary side 18 alternating magnetic field of reception.Thus provide " being galvanically isolated " supply voltage for second circuit part 3 in primary side 18.The supply voltage that such as at least the first photoelectrical coupler 15 can be galvanically isolated drives, and is Specifically long-time driving.
The d. c. voltage signal through over commutation of the first circuit part is additionally operable to the power supply of Switching Power Supply part 9, and it thus produces the constant power voltage for master controller 13.
When disabling or turn off this home appliances H, home appliances is in resting state, and now switch 21 is first switched on, thus it disconnects the circuit between the primary side 18 and power elements 24 of transformator 8.The third circuit portion 10 being made up of power elements 24 and satellite controller 28 is thus opened and not power consumption with the supply voltage partition being galvanically isolated.
Along with being enabled or switched on or along with selecting a driver needing second circuit part 3 of home appliances H, master controller 13 causes and satellite controller 28 communication and the data signal input to the first photoelectrical coupler 15 sending especially data for this through its signal output part 14.Therefore, the outfan at the first photoelectrical coupler 15 produces signal associated therewith, and this signal arrives the secondary signal input 30 of satellite controller 28 by branch 32 1 aspect, arrives the input of self-contained unit 35 on the other hand.
Because satellite controller 28 is not yet powered, therefore do not have to utilize the signal received there.But self-contained unit 35 utilizes the data signal arrived as control signal to send the control signal control input 26 to switch 21 by its control output end 36, switchs 21 Guan Bis subsequently and thereby turns on the circuit between the primary side 18 and power elements 24 of transformator 8.Therefore, power elements 24 can by the supply voltage being galvanically isolated for producing to be used for driving the supply voltage of satellite controller 28 on its power supply outfan 27.Thus satellite controller 28 preheating operation send signal (such as more new signal) by the 3rd signal output part 31, this signal is received at self-contained unit 35 place and for keeping self-contained unit 35 to enable and maintained switch 21 closes.That is, it is provided that the self-holding function of satellite controller 28, it is started by master controller 13.It addition, the data signal separated at place of branch 32 of master controller 13 or the first photoelectrical coupler 15 is received and can be used as additional more new signal.
In order to disconnect or disable third circuit portion 10, it is particularly possible to sent shutoff instruction to satellite controller 28 by master controller 13 by its signal output part 14, no longer have signal to be issued through signal output part 14 subsequently.That is, the signal output part 14 of master controller 13 especially switches to after sending shutoff instruction and mourns in silence.Along with receiving shutoff instruction, satellite controller 28 such as terminate its still run process and subsequently self-contained unit 35 discharge (that is not sending signal then through its 3rd signal input part 31).By discharging self-contained unit 35, switch 21 is opened after the self-holding time specified by self-contained unit 35 and interrupts the power supply to third circuit portion 10.The self-holding time such as can depend on the design size of corresponding electric storage means.
Circuit 1 has the following advantages, it allow according to simple application mode by having at least time turn-off current isolation section or part realize economize on electricity probability.Therefore, at least described power elements 24 and satellite controller 28 partition of can powering with it is opened in the circuit 1.This can realize without additional communication channels.
