Fig. 3, Fig. 4 show the view that is applied to according to first and second embodiment of the electric supply installation of reciprocating compressor of the present invention.
Power supply unit comprises: rectification part 202, and it is used for the AC electric energy of rectification from 201 supplies of AC power supply unit; DC link section 203, it is used for stable by the electric energy of rectification; And inverter switching device unit 204, it is used to control the electric energy that is applied to coil portion 205.The AC electric energy is supplied from the external world by the AC power supply unit 201 such as electric wire, cable etc. usually.Rectification part 202 plays the effect of rectification AC electric energy, thereby the AC electric energy is only flowed along a direction, and DC link section 203 plays and reduces by the effect of the amplitude variations of rectification electric energy (playing stable effect).Because the purpose of rectification part 202 and DC link section 203 is that the AC electric energy is converted to stable DC electric energy, therefore, rectification part 202 and DC link section 203 can be combined into the electric energy converting unit.The electric energy that inverter switching device unit 204 applies by a plurality of switch controls.Controlled electric energy is converted to the AC electric energy with suitable amplitude and frequency by inverter switching device unit 204, and the AC electric energy is applied to coil portion 205 (corresponding to the winding body 14a of Fig. 2).
Fig. 3 shows the view that is applied to according to first embodiment of the electric supply installation of reciprocating compressor of the present invention.
Although rectification part 202 plays the effect of rectification AC electric energy, and in Fig. 3, rectification part 202 constitutes by four diodes are connected to a full bridge structure, but, the structure of this rectification part is a known technology, therefore, any effect that can play rectification AC electric energy all is available along the structure that a direction flows only thereby make the AC electric energy.
If the first capacitor C1 and the second capacitor C2 have big electric capacity, even then applied the voltage that significantly changes from rectification part 202, the both end voltage V/2 of the first capacitor C1 and the second capacitor C2 can not be subjected to too much influence yet.If the absolute value of the voltage of the first capacitor C1 or the second capacitor C2 is less than the absolute value of the electric energy that passes through rectification part 202, then the diode of rectification part 202 is closed, and the voltage of DC link section 203 is applied to inverter switching device unit 204.Otherwise, if the absolute value of the voltage of the first capacitor C1 or the second capacitor C2 is greater than the absolute value of the electric energy that passes through rectification part 202, then the diode of rectification part 202 is closed, and the voltage of DC link section 203 is subjected to the influence by the electric energy of rectification part 202, therefore, the voltage by rectification part 202 is applied in to inverter switching device unit 204.Handle by this, can reduce the amplitude of variation of voltage.
Inverter switching device unit 204 is made up of first switch (or the first inverter switching device) S1 and second switch (or the second inverter switching device) S2 that are used for to coil portion 205 power supplies.The two ends of inverter switching device unit 204 are connected in the two ends of DC link section 203.That is, the end of first switch S 1 and second switch S2 is connected to capacitor C1, the C2 of DC link section 203, and the other end of first switch S 1 and second switch S2 is connected in coil portion 205.Coil portion 205 is connected between the tie point of the tie point of the first capacitor C1 and the second capacitor C2 and first switch S 1 and second switch S2.
Electric energy by first switch S 1 and second switch S2 control is converted into the AC electric energy with suitable amplitude and frequency, and the AC electric energy is applied in to coil portion 205.The coil portion 205 of Fig. 3 shows coil portion 14a briefly.When control inverter switch element 204, the control unit (not shown) of reciprocating compressor is opening/closing first switch S 1 and second switch S2 alternately, to impose on coil portion 205 from the electric energy of DC link section 203 with this, suction stroke, compression travel, the discharging stroke of finishing reciprocating compressor thus continuously reach expansion stroke again.For example, when first switch S 1 is in open mode or opening operation, when second switch S2 is in closed condition or shutoff operation, voltage+V/2 is applied in to coil portion 205, thereby finish again expansion stroke and suction stroke continuously, and ought first switch S 1 be in closed condition or shutoff operation, when second switch S2 is in open mode or opening operation, voltage-V/2 is applied in to coil portion 205, thereby finishes compression travel and discharging stroke continuously.
By this structure, although the quantity of inverter switching device reduces to two from four, also can provide with conventional art in identical effect.Even AC power supply unit 201 applies the voltage that amplitude is V by rectification part 202, if first switch S 1 or second switch S2 are in open mode or opening operation, the voltage that is applied to the first capacitor C1 and the second capacitor C2 from DC link section 203 is reduced to V/2 so, promptly, its half size makes efficient reduce thus.Be head it off, disclose second embodiment.
Fig. 4 is the view that shows second embodiment of the electric supply installation that is applied to reciprocating compressor of the present invention.
Therefore the connection of DC link section 203 and inverter switching device unit 204 and function and shown in Figure 3 identical will omit the description to it.In rectification part 202, the Section Point 102 that is connected in AC power supplies 201 is connected in the grounded part of DC link section 203, that is, and and the tie point of the first capacitor C1 and the second capacitor C2.Therefore, the grounded part of DC link section 203 is connected with the grounded part of AC power supplies 201, and the voltage of Section Point 102 is always zero.In addition, all the structure with previous embodiment is identical for the structure of rectification part.Therefore, first capacitor C1 of DC link section 203 and the both end voltage of the second capacitor C2 are increased to V, and this voltage V is applied to coil portion 205.
In second embodiment of Fig. 4, first switch S 1 and second switch S2 be equally by opening/closing alternately, finishes the suction stroke, compression travel, discharging stroke of reciprocating compressor and expansion stroke more thus continuously.
If the voltage of first node 101 is higher than the voltage of the 3rd node 103, then electric energy flows towards the 3rd node, so that the voltage of the 3rd node equates with the voltage of AC power supplies 201.If the voltage of first node 101 is lower than the voltage of the 4th node 104, then electric energy flows from the 4th node 104, so that the voltage of the 4th node 104 equates with the voltage of AC power supplies 201.If the voltage of first node 101 is between the voltage of the voltage of the 3rd node 103 and the 4th node, then all diodes are all closed.If the electric capacity of the capacitor of formation DC link section 203 is big, the voltage of DC link section 203 can not change too much so.Handle by this, make the amplitude of variation that is applied to the voltage of inverter switching device unit 204 by DC link section 203 reduce.Stable DC electric energy is converted to the AC electric energy Vm with suitable amplitude and frequency by inverter switching device unit 204, and AC electric energy Vm is applied to coil portion 205.
In this specification, although do not describe the control unit that is used for according to pwm signal control inverter switch element 204, the structure of this control unit is known to those skilled in the art.
Below reference example and accompanying drawing have been done detailed explanation to the present invention.Yet scope of the present invention is not limited to these embodiment and accompanying drawing, but is limited by appending claims.
