Patent documentation 1: TOHKEMY 2004-154961 communique.
Use in the supply unit in the motor driven with resistance regeneration and power supply regenerative and usefulness shown in Figure 5, under the situation that in power supply regenerative, has produced instantaneous power-off, because the AC supply voltage step-down, so the power supply regenerative electrorheological is too much.Therefore, produce the alarm of expression overcurrent by this situation, damage the employed transistor of the transducer of working sometimes being used for power supply regenerative.Under the state of resistance reproduction operation, if power up, then the direct voltage of inverter becomes high state when producing instantaneous power-off.If carry out power supply regenerative this moment, then the power supply regenerative electric current become excessive, thereby the alarm that produces the expression overcurrent damages transistor sometimes.
Summary of the invention
The present invention proposes in view of the above problems.The object of the present invention is to provide the renovation process of a kind of motor driven, power supply regenerative is stopped and switching to resistance even it under the situation that has produced instantaneous power-off, also can not become overcurrent and regenerate with supply unit and this device of use.
Except above-mentioned purpose, other purposes of the present invention are to provide the renovation process of a kind of motor driven with supply unit and this device of use, even it under situation about recovering, can not become overcurrent yet from instantaneous power-off, can carry out the transition to power supply regenerative from resistance regeneration.
Motor driven supply unit of the present invention comprises that power circuit, regeneration resistance circuit and Continuity signal produce circuit.Power circuit has and will be transformed to direct current from the alternating current that exchanges power supply and direct current power supplied with the rectification function of control device of electric motor and comprise the converter circuit of a plurality of thyristors and will regenerate to the regeneration function of AC power from the regenerated electric power of control device of electric motor side regeneration by use.The regeneration resistance circuit is made of the series circuit of regeneration resistance and switching circuit, is arranged between dc output end of power circuit, becomes conducting state by making switching circuit, by described regeneration resistance consumption regenerated electric power.Continuity signal produces circuit, is used for when regeneration, is created in first Continuity signal that is used for control transformation device circuit when carrying out power supply regenerative and second Continuity signal that is used for the conducting of control switch circuit when carrying out resistance regeneration.
According to the present invention, Continuity signal produces circuit, when regeneration, when the voltage difference between the supply voltage peak value of direct voltage between the direct current input part of control device of electric motor and AC power than with instantaneous power-off as benchmark and predefined reference voltage when big, stop the output of first Continuity signal, converter circuit is made as non operating state, during the output that has stopped first Continuity signal, exports second Continuity signal.Continuity signal produces circuit, as above exports first Continuity signal and second Continuity signal like that, when having produced instantaneous power-off, power supply regenerative is stopped, and regenerates from birth by resistance again.Therefore, even because instantaneous power-off, the DC voltage rising of the input side of control device of electric motor is in the thyristor of the converter circuit that is used for the carrying out power supply regenerative overcurrent that also can not flow.Owing to when instantaneous power-off, carry out resistance regeneration, therefore can provide a kind of motor driven supply unit with the high regeneration function of reliability.
Aforesaid reference voltage can be set at and make it possible to stop the overcurrent that flows in the employed thyristor of converter circuit.Particularly, can determine reference voltage according to the performance of the thyristor that uses and the standard of power supply.

The present invention can grasp as the renovation process of aforesaid motor with drive unit.In the method for the invention, when regeneration, when instantaneous power-off has taken place, stop the work of converter circuit, during converter circuit is out-of-work, only regenerate by the regeneration resistance circuit.Therefore, even when instantaneous power-off has taken place, can Parallel Implementation constitute the protection and the regeneration control of the thyristor of converter circuit.
Even after instantaneous power-off recovers, also there is the situation that is in the high state of direct voltage.Therefore, even after instantaneous power-off recovers, voltage difference between the direct voltage between the direct current input part of control device of electric motor and the supply voltage peak value of AC power than with instantaneous power-off as benchmark and predefined reference voltage when big, do not restart the work of converter circuit yet, only in the regeneration resistance circuit, regenerate.Like this, just can prevent reliably that overcurrent from flowing in the thyristor of converter circuit.
Clearly, after instantaneous power-off recovers, voltage difference between the supply voltage peak value of direct voltage between the direct current input part of control device of electric motor and AC power than with instantaneous power-off as benchmark and predefined reference voltage hour, and use power supply regenerative.

Embodiment
Fig. 1 is the schematic diagram of expression motor driven of the present invention with the summary formation of an example of the execution mode of supply unit.Connect AC reactor ACL on three-phase alternating-current supply AC, bridging meets 6 transistor Tr 1～Tr6 as thyristor in its output, constitutes converter circuit CV.6 diode D1～D6 then are connected in parallel respectively on 6 transistor Tr 1～Tr6.6 diode D1～D6 constitute the rectified three-phase circuit that bridging connects.By transistor Tr 1～Tr6 and the diode D1～D6 that bridging connects, constitute power supply regenerative circuit PR.
Between dc output end of converter circuit CV, the series circuit that has been connected in parallel, this series circuit is for the regeneration resistance R and constitute the transistor Tr 7 of switching circuit and the series circuit of the parallel circuits of diode D7.This series circuit constitutes resistance regenerative circuit RR.Resistance regenerative circuit RR is constituted as and makes by making transistor Tr 7 (switching circuit) become conducting state cause regeneration resistance R consumption regenerated electric power.
Smmothing capacitor C has been connected in parallel between dc output end of converter circuit CV.At the two ends of smmothing capacitor C, connected the control device of electric motor MC that comprises inverter circuit.This inverter circuit becomes to exchange with DC converting, thereby the three-phase alternating current of preset frequency is offered three-phase alternating-current motor M as motor current.Inverter circuit slows down and when becoming reproduced state at motor M, is transformed to the transducer of direct current and works as the alternating current with motor M generating.
The outlet side of the AC reactor ACL that is connected with the T phase mutually in R phase, S has connected PD of phase-detection portion and supply voltage peak value test section VHD.Be provided with direct voltage test section VD, its both end voltage that is used to measure smmothing capacitor C is the direct voltage of the input side of control device of electric motor MC.
The output of direct voltage test section VD, the PD of phase-detection portion and supply voltage peak value test section VHD is imported into Continuity signal and produces circuit SG.When Continuity signal produces circuit SG and is created in motor M traction and when regeneration, be used for making a plurality of first Continuity signal S and when regeneration, being used for of 6 transistor Tr 1～Tr6 conducting of the transducer that constitutes power supply regenerative circuit PR to make the transistor Tr 7 of resistance regenerative circuit RR become the second Continuity signal S ' of conducting state.In the present embodiment, Continuity signal produces circuit SG, when regeneration, when the voltage difference delta V between the supply voltage peak value Vp of direct voltage Vdc between the direct current input part of control device of electric motor MC and AC power AC than with instantaneous power-off as benchmark and predefined reference voltage V r when big, stop the output of the first Continuity signal S, converter circuit among the power supply regenerative circuit PR is made as non operating state, during the output that has stopped the first Continuity signal S, export the second Continuity signal S '.Produce among the circuit SG at Continuity signal, the first Continuity signal S generates in the first Continuity signal generating unit CS1 and exports, and the second Continuity signal S ' generates in the second Continuity signal generating unit CS2 and exports.The first Continuity signal generating unit CS1 can produce with existing power supply regenerative circuit for example shown in Figure 4 in the identical signal of employed signal (Continuity signal).For the effect that obtains stipulating, clearly, the first Continuity signal generating unit CS1 produces some phase places first Continuity signal S different with signal (Continuity signal) shown in Figure 4.
In the present embodiment, Continuity signal generation circuit SG also comprises voltage difference operational part DV and instruction generating unit CG.Voltage difference operational part DV tries to achieve the voltage difference delta V between the direct voltage Vdc that supply voltage peak value Vp that supply voltage peak value test section VHD detects and direct voltage test section VD detect.Instruction generating unit CG compares voltage difference delta V and reference voltage V r, at voltage difference delta V is reference voltage V r or when following, output is used to instruct the output order of output of the first Continuity signal S, when voltage difference delta V is bigger than reference voltage V r, produce the output halt instruction be used to instruct the output of the first Continuity signal S to stop.The first Continuity signal generating unit CS1 is constituted as the phase place of the supply voltage that detects based on the PD of phase-detection portion, produce the first turn-on command S, when output order is transfused to, the first Continuity signal S is outputed to converter circuit, when the output halt instruction is transfused to, stop the first Continuity signal S is outputed to converter circuit.The second turn-on command generating unit CS2 is constituted as at direct voltage Vdc and becomes the first predetermined reference dc voltage Vr1 or when above, export the second Continuity signal S ', become the predetermined second reference dc voltage Vr2 lower when following at direct voltage Vdc, stop the output of the second Continuity signal S ' than the first reference dc voltage Vr1.
Continuity signal produces circuit SG, as above exports the first Continuity signal S and the second Continuity signal S ' like that, when having produced instantaneous power-off, the work of power supply regenerative circuit PR is stopped, and RR regenerates by the resistance regenerative circuit.Therefore, even because instantaneous power-off, the direct voltage Vdc of the input side of control device of electric motor MC rises, and overcurrent can not flow among the transistor Tr 1～Tr6 of the converter circuit CV in power supply regenerative circuit PR yet.Because resistance regenerative circuit RR carries out reproduction operation when instantaneous power-off, therefore can keep the high regeneration control of reliability.
Even after instantaneous power-off recovers, also there is the high state of direct voltage that is in.Therefore, instruction generating unit CG can continue to export halt instruction, even make after instantaneous power-off recovers, voltage difference between the direct voltage between the direct current input part of control device of electric motor and the supply voltage peak value of AC power than with instantaneous power-off as benchmark and predefined reference voltage when big, do not restart the work of converter circuit CV, only in the regeneration resistance circuit, regenerate.If become like this, just can prevent reliably that overcurrent from flowing in the thyristor of converter circuit.Clearly, after instantaneous power-off recovers, voltage difference between the supply voltage peak value of direct voltage between the direct current input part of control device of electric motor and AC power than with instantaneous power-off as benchmark and predefined reference voltage hour can and be used power supply regenerative.In this case, for example, voltage difference delta V between the direct voltage Vdc that supply voltage peak value Vp and direct voltage test section VD detect becomes the recovery reference voltage lower than reference voltage V r when following, instruction generating unit CG can export output order, restarts the work of converter circuit CV.
Below, use Fig. 2 that the work of Fig. 1 execution mode is described simply.Fig. 2 is the working waveform figure of supposing in the way that motor is a significant slowdown under the situation that instantaneous power-off has taken place.When motor M carried out running under power, the grid of transistor Tr 1～Tr6 became disconnection.Afterwards, three-phase alternating-current supply AC carries out three phase full wave rectification by the diode D1～D6 that is connected in parallel with transistor Tr 1～Tr6, and electric power is supplied with control device of electric motor MC.When motor M becomes deceleration regime, become reproduced state, regenerated electric power turns back to mains side from motor M, and the voltage of the direct current portion of control device of electric motor MC rises.Then, based on the phase place of the three-phase alternating voltage that is detected by the PD of phase-detection portion, transistor Tr 1～Tr6 becomes conducting state in the conduction period by Continuity signal S1～S6 appointment.Its result, regenerative current flows mutually at each, thereby will make the regenerated electric power of the voltage rising of direct current portion turn back to power supply AC.If instantaneous power-off does not have the situation of generation, then when being caused that by regeneration direct voltage Vdc rises, power supply regenerative work is repeated to carry out.Therefore, in the present embodiment, carry out power supply regenerative work usually.
Under the situation that instantaneous power-off has taken place in power supply regenerative, shown in Fig. 2 (B), supply voltage peak value Vp reduces, and shown in Fig. 2 (C), the direct voltage Vdc of the direct current portion of control device of electric motor MC rises.Then, difference between direct voltage Vdc and supply voltage peak value Vp becomes reference voltage V r or when above, the supply of the signal (Continuity signal) of the transistor Tr 1～Tr6 of the converter circuit in constituting power supply regenerative circuit PR is stopped (stopping period is called interlocking (interlock)).Fig. 2 (D) show interlocking during.When the direct voltage Vdc of the direct current portion of control device of electric motor MC has surpassed resistance reproduction operation voltage Vr1, resistance regenerative circuit RR work.The second Continuity signal S ' that is used for the transistor Tr 7 of controlling resistance regenerative circuit RR, when direct voltage Vdc becomes the first reference voltage V r1, make transistor Tr 7 conductings, become than the second reference voltage V r2 hour, make transistor Tr 7 non-conduction at direct voltage Vdc.Because this work repeats, so the direct voltage Vdc of the control device of electric motor of Fig. 2 (C) changes in during interlocking.Even instantaneous power-off recovers, the difference between supply voltage peak value Vp and direct voltage Vdc is in big time, the state after the supply of the first Continuity signal S of the converter circuit CV of power supply regenerative circuit PR becomes interlocking and applies.When electromotor velocity reduces, regenerated electric power from motor diminishes, thereby direct voltage Vdc reduces, and the difference between the supply voltage peak value Vp is when diminishing, instruction generating unit CG exports output order, and this output order instruction outputs to power supply regenerative circuit PR with the first Continuity signal S.At this moment, because the difference between direct voltage Vdc and the supply voltage peak value Vp is little, therefore can not become overcurrent.
In the present embodiment, AC reactor ACL is also configurable in the back of comparing with the tie point of the PD of phase-detection portion (power supply regenerative circuit PR side).
According to above-mentioned execution mode, in supply unit with resistance regeneration and power supply regenerative and usefulness, under the big situation of the direct voltage Vdc of control device of electric motor and the poor Δ V between the supply voltage peak value Vp, on the Continuity signal of power supply regenerative circuit PR, apply interlocking, when the Δ V that is on duty diminishes, remove interlocking.Thus, even instantaneous power-off has taken place, the source current of supply unit becomes excessive, can represent the alarm of overcurrent again, also can not damage transistor Tr 1～Tr6, thereby can realize the power supply regenerative device that reliability is high.
Industrial applicibility
According to the present invention, Continuity signal produces circuit, when regeneration, when the voltage difference between the supply voltage peak value of the DC voltage between the direct current input part of control device of electric motor and AC power than with instantaneous power-off as benchmark and predefined reference voltage when big, stop the output of first Continuity signal, converter circuit is made as off working state, during the output that has stopped the first Continuity signal S, only export second Continuity signal, therefore, when instantaneous power-off had taken place, power supply regenerative was stopped, and was only regenerated from birth by resistance again. Therefore, even the DC voltage rising of the input side of the control device of electric motor that is caused by instantaneous power-off, overcurrent can not flow in the thyristor of the converter circuit of carrying out power supply regenerative yet. Owing to when instantaneous power-off, carry out resistance regeneration, therefore can provide the Motor Drive supply unit with the high regeneration function of reliability.
