Embodiment, belong to the scope of protection of the invention.
In the prior art, for the DRIVEN BY AIR CONDITIONING COMPRESSOR system of no electrolytic capacitor, due to eliminating electrolysis electricity
Hold, easily cause the dc bus of DRIVEN BY AIR CONDITIONING COMPRESSOR system to produce larger fluctuation, this fluctuation is easy to be delivered to compressor
Side, so as to cause compressor operating unstable, increase control difficulty；Simultaneously because DC bus-bar voltage fluctuation is larger, work as pressure
When contracting machine operates in high-frequency section, DC voltage trough can not ensure the driven of compressor, it is necessary to carry out the weak magnetic of depth
Control, just it is avoided that compressor is in inertial rotation state, and the control of depth weak magnetic will necessarily substantially reduce compressor efficiency.
The existing high frequency range of operation for improving no electrolytic capacitor scheme typically has two methods：First is to weight of compressor
Newly it is designed, makes it have relatively low back-emf, so as to meets the requirement of the fan-out capability of high-frequency section.The shortcomings of doing so exists
In the parameter change that redesign can be to existing compressor is larger, and proving period is longer；And the relatively low compressor of back-emf,
Need input current larger, compressor efficiency can be influenceed.Second is to use ovennodulation control technology to improve voltage utilization, and
Depth weak magnetic control technology is coordinated to be controlled.But the control of depth weak magnetic is needed to inject extra electric current into motor, and this can be produced
Raw extra loss, can also influence compressor efficiency.
The embodiment of the present invention provides a kind of DRIVEN BY AIR CONDITIONING COMPRESSOR system, including：First DC power supplier 10, first is thin
Membrane capacitance 11, the first inverter bridge 12, open the inverter bridge 14 of winding electric machine 13 and second；The first film electric capacity 11, the first inverter bridge 12

With reference to shown in figure 4 and Fig. 5, winding electric machine 13 is opened compared to traditional star winding motor, eliminates the public affairs of winding
CMP, the winding other end is also drawn inside compressor of air conditioner.So when the S1-1 and second of the first inverter bridge 12 is inverse
When becoming the S2-4 of bridge 14 while opening, winding U1U2 phase voltage maximums fundamental voltage amplitude is Udc；Similarly for winding V1V2 and W1W2,
Its phase voltage maximum fundamental voltage amplitude can also equally reach Udc, so that the voltage utilization for opening winding electric machine 13 improves one
Times.
This high voltage utilization rate characteristic causes the DRIVEN BY AIR CONDITIONING COMPRESSOR system of no electrolytic capacitor to redesign pressure
Contracting machine parameter, it still can meet the fan-out capability requirement of high-frequency section.Fig. 6 show the air-conditioning pressure of traditional no electrolytic capacitor
The voltage characteristic schematic diagram of contracting machine drive system；Wherein K1For voltage utilization, UdcFor DC bus-bar voltage, E0It is anti-electric for motor
Gesture, work as K1Udc>E0When, can be with driven compressor；And work as K1Udc<E0When, it is necessary to it can just be met by the control of depth weak magnetic
The requirement of high frequency operation.And the voltage characteristic of the DRIVEN BY AIR CONDITIONING COMPRESSOR system of the no electrolytic capacitor in the embodiment of the present invention is as schemed
Shown in 7, due to improving voltage utilization K2So that effective voltage curve integrally moves up, most of to be more than winding back emf E0,
Therefore compressor parameter need not be redesigned, also avoids loss increase problem caused by low back-emf motor；And
Only need a small amount of weak magnetic or do not need weak magnetic also to realize that compressor high frequency is run.
With reference to shown in figure 4, the first DC power supplier 10 is used to provide DC voltage, and the first DC power supplier 10 can be with
It is that a direct voltage source or the modular structure being made up of alternating-current voltage source and PFC, the embodiment of the present invention are not done to this
Limit.
So, compared to prior art, DRIVEN BY AIR CONDITIONING COMPRESSOR system in the embodiment of the present invention as a result of

Winding electric machine, the voltage utilization for opening winding electric machine improve one times so that the permanent torque area of compressor of air conditioner have also been enlarged one
Times, and then compressor of air conditioner may operate under higher frequency, that is, improve the running frequency and fortune of compressor of air conditioner
Line efficiency, and then improve air-conditioning efficiency；Simultaneously as traditional electrochemical capacitor volume is substituted in the embodiment of the present invention

The small volume of DRIVEN BY AIR CONDITIONING COMPRESSOR system, while reduce cost.
Wherein, the first rectifier bridge 17 is full bridge structure.
In actual applications, it can be permagnetic synchronous motor or asynchronous machine to open winding electric machine 13, and the present invention is real
Example is applied not limit this.Because the power of permagnetic synchronous motor unit volume is bigger, torque fluctuations are small, and operational efficiency
It is high so that using the compressor of permagnetic synchronous motor in refrigeration, heating it is more steady, noise is smaller, and operational efficiency is higher,
Energy-saving effect is more preferably.Thus preferably, opening winding electric machine 13 to drive winding permanent magnet synchronous motor.

Presence can influence to hold the current waveform of winding electric machine 13, torque ripple and the loss of winding electric machine 13 are opened in increase, this it is split around
Group motor 13 is harmful, thus needs to be suppressed from algorithm, but can so increase the difficulty of control again；And in Figure 10
Double power-supply system can fundamentally suppress the generation of zero-sequence current, without being suppressed using algorithm, and then reduce
Control difficulty.
It should be noted that the dc bus of the first inverter bridge 12 and the second inverter bridge 14 can link together, also may be used
To be not attached to together, the embodiment of the present invention is not limited this.The direct current of first inverter bridge 12 and the second inverter bridge 14 is female
The structure that line links together is properly termed as common bus structure；By the dc bus of the first inverter bridge 12 and the second inverter bridge 14 not
The structure to link together is properly termed as isolating bus structure, as shown in Figure 10.
In actual applications, it can be permagnetic synchronous motor or asynchronous machine to open winding electric machine 13, and the present invention is real
Example is applied not limit this.Because the power of permagnetic synchronous motor unit volume is bigger, torque fluctuations are small, and operational efficiency
It is high so that using the compressor of permagnetic synchronous motor in refrigeration, heating it is more steady, noise is smaller, and operational efficiency is higher,
Energy-saving effect is more preferably.Thus preferably, opening winding electric machine 13 to drive winding permanent magnet synchronous motor.
With reference to shown in figure 10, open winding electric machine 13 compared to traditional star winding motor, eliminate winding it is public in
Heart point, the winding other end is also drawn inside compressor of air conditioner.So as the S1-1 and the second inverter bridge of the first inverter bridge 12
14 S2-4 is opened simultaneously when, winding U1U2 phase voltage maximums fundamental voltage amplitude is Udc；Similarly for winding V1V2 and W1W2, its phase
Voltage maximum fundamental voltage amplitude can also equally reach Udc, so that the voltage utilization for opening winding electric machine 13 is doubled.
This high voltage utilization rate characteristic causes the DRIVEN BY AIR CONDITIONING COMPRESSOR system of no electrolytic capacitor to redesign compressor parameter,
Still the fan-out capability requirement of high-frequency section can be met.Due to compressor parameter need not be redesigned, also avoid low
Loss increase problem caused by back-emf motor；And only need a small amount of weak magnetic or do not need weak magnetic also to realize compressor height
Frequency is run.
So, compared to prior art, DRIVEN BY AIR CONDITIONING COMPRESSOR system in the embodiment of the present invention as a result of
