Embodiment
[1] following with reference to accompanying drawing, describe the 1st embodiment of the present invention in detail.
As shown in Figure 1, on commercial ac power source 1, connect rectification circuit 2, on the output of this rectification circuit 2, connect switching circuit 4 by filtering capacitor 3.
On lead-out terminal Qu, the Qv of this switching circuit 4, Qw, be connected with phase winding Lu, Lv, Lw as 3 phase brushless DC motor M.3 phase brushless DC motor M comprise: have 3 phase winding Lu, Lv of star connection, Y connection, the stator of Lw, and the rotor with permanent magnet.Interaction owing to flowing through the magnetic field that electric current produces and be fixed on the magnetic field that epitrochanterian permanent magnet produces in phase winding Lu, Lv, Lw makes the rotor rotation.
This 3 phase brushless DC motor M is installed in refrigerating circulating apparatus, for example on the compressor 31 of air conditioner 30.Compressor 31 is by the action of 3 phase brushless DC motor M, and suction refrigerant also compresses, sprays.During refrigeration, as shown shown in the solid arrow, the refrigerant of ejection flow in the outdoor heat converter 33 that uses as condenser by cross valve 32 from compressor 31, the refrigerant of this outdoor heat converter 33 of process flow in the indoor heat converter 35 that uses as evaporator by the expansion valve 34 as decompressor.Refrigerant through indoor heat converter 35 is inhaled into compressor 31 by above-mentioned cross valve 32.And compressor 31, cross valve 32, outdoor heat converter 33, expansion valve 34, indoor heat converter 35 utilize the refrigerant pipeline that is made of copper pipe etc. to connect.During heating, as shown shown in the dotted arrow, flow into the indoor heat converter 35 that uses as condenser from the refrigerant of compressor 31 ejections by cross valve 32, the refrigerant that has passed through this indoor heat converter 35 flow into the outdoor heat converter 33 that uses as evaporator by expansion valve 34.The refrigerant that has passed through outdoor heat converter 33 is inhaled in the compressor 31 by above-mentioned cross valve 32.
The voltage of phase winding Lu, the Lv of position of rotation test section 11 detections 3 phase brushless DC motor M, the phase winding induction of the non-power status among the Lw according to the variation of this induced voltage, detects the rotor rotation position of 3 phase brushless DC motor M.Its testing result is supplied to convertor device control part 10.
Convertor controls portion 10 is according to position of rotation test section 11 detected position of rotation, generate frequency change and phase angle and differ 120 three sine voltages of spending, by carrying out pulse-width modulation (PW M) based on these sine voltages with as the voltage ratio of the triangular signal of the assigned frequency F of carrier wave, generate three drive signals (pulse-width signal) thus, be used to make switching circuit 4 each transistor turns, end.Utilize this three drive signals, the transistor of at least 1 series circuit in the switching circuit 4 is switched on and off, make a plurality of energisings mutually of the transistor turns of at least one other series circuit, switch successively.Utilize this a plurality of switchings (the so-called change of current) of energising mutually, at three voltages between phases (the sinusoidal wave voltage that changes) of the mutual generation of lead-out terminal Qu, Qv, the Qw level corresponding with transistorized conduction and cut-off duty ratio.These voltages between phases are added on phase winding Lu, Lv, the Lw, make on phase winding Lu, Lv, the Lw to flow through sine-wave current the rotor rotation of 3 phase brushless DC motor M.
Transistorized conduction and cut-off duty ratio changes with the voltage level of three sine voltages of above-mentioned generation.According to the rotary speed instruction signal that the Equipment Control portion 36 from air conditioner 30 supplies with, regulate this voltage level.That is to say, increase at air conditioner load that need make under the situation of compressor capacity increase, the voltage level of each sine voltage is regulated to ascent direction, the conduction and cut-off duty ratio increases (increase during the connection, shorten between the off period).If the conduction and cut-off duty ratio increases, then the level of each voltage between phases increases, and the phase winding electric current increases.Thereupon, the rotating speed of 3 phase brushless DC motor M improves.Reduce at air conditioner load, need reduce under the situation of compressor capacity, the voltage level of each sine voltage is regulated to descent direction, and the conduction and cut-off duty ratio reduces (shorten turn-on time, and increase opening time).If the conduction and cut-off duty ratio reduces, then the level of each voltage between phases reduces, and the phase winding electric current reduces.Thereupon, the rotating speed of 3 phase brushless DC motor M reduces.
Carry out like this from the what is called 120 degree energisings of switching circuit 4 to 3 phase brushless DC motor M.This 120 degree energising is under the situation of 4 utmost point d.c. motors at 3 phase brushless DC motor M, and when repeating 2 times, 3 phase brushless DC motor M revolve and turn around from cycle (electrical degree 360 degree) of the voltage between phases of switching circuit 4 outputs.At 3 phase brushless DC motor M is under the situation of 6 utmost point d.c. motors, and when repeating 3 times from cycle of the voltage between phases of switching circuit 4 output, 3 utmost point brushless DC motor M revolve and turn around.
On the other hand, the testing result of position of rotation test section 11 is fed into number of poles judging part 20.Number of poles judging part 20 is judged the number of poles of three-phase brushless DC motor M according to the load change in the circle of three-phase brushless DC motor M, comprising: heavy load test section 21, timer 22 and judging part 23.
Repeat lotus judging part 21 testing results according to position of rotation test section 11, come respectively each cycle of the output of switching circuit 4 (sinuous voltage between phases) (rotating machinery angle 180 degree that are equivalent to electrical degree 360 degree=4 utmost point d.c. motors) to be divided into 6 intervals (rotating machinery angle 30 degree that are equivalent to 4 utmost point d.c. motors), in (36 interval), the load that detects above-mentioned compressor 31 becomes heavy interval (between the compression period of compressor 31) between the whole district at least 6 cycles of same output.Be set in 6 intervals in each cycle corresponding to above-mentioned a plurality of each step modes of energising mutually.Load at compressor 31 becomes heavy interval (between so-called heavy loading district), and the speed of the rotor of three-phase brushless DC motor M descends.From each interval begin calculate by timer 22 respectively to the time that finishes, calculate the poor of 2 adjacent in each timing timing successively, the difference that calculates is detected as repeating the lotus interval from increasing to reducing the interval (between peak region) that changes.
23 pairs of judging parts are calculated by the quantity between heavy load test section 21 detected heavy loading districts, according to the counting in 6 cycles, the number of poles of judging three-phase brushless DC motor M is 4 utmost points or 6 utmost points, and compressor 31 is 1 cylinder rotary types, still 2 cylinder rotary types.
The load change in the 1 circle rotation of 4 utmost point d.c. motors and the relation of step mode are divided into helicoid situation of 1 cylinder and the helicoid situation of 2 cylinders, are shown in Fig. 2 respectively.It is compression travel before the ejection that load becomes the heaviest.Therefore, in 1 cylinder rotary type, the quantity of (also can be described as between peak region) is " 1 " between the heavy loading district in the motor 1 circle rotation, and in 2 cylinder rotary types, enclose in the rotation owing to producing 2 compressions, spraying stroke, at motor 1 so the quantity between the heavy loading district becomes " 2 ".
The load change in 6 cycles of output of convertor device and the relation of step mode are divided into the situation of the helicoid situation of 1 cylinder, the helicoid situation of 2 cylinders, 4 utmost point d.c. motors, the situation of 6 utmost point d.c. motors, are shown in Fig. 3.In 1 cylinder rotary type, during 4 utmost point d.c. motors, the quantity of (between peak region) between the heavy loading district (peak value number of times) becomes " 3 ".In 1 cylinder rotary type, during 6 utmost point d.c. motors, the quantity between the heavy loading district becomes " 2 ".In 2 cylinder rotary types, during 4 utmost point d.c. motors, the quantity between the heavy loading district becomes " 6 ".When 2 cylinder rotary types, 6 utmost point d.c. motors, the quantity between the heavy loading district becomes " 4 ".So according to the quantity between this heavy loading district in 6 cycles of output of convertor device, judge the mode of compressor and the number of poles of motor by judging part 23.
Utilize above rectification circuit 2, filtering capacitor 3, switching circuit 4, convertor controls portion 10, position of rotation test section 11 and number of poles judging part 20, constitute the convertor device that three-phase brushless DC motor M is carried out variable speed drive.
Below, with reference to the flow chart of Fig. 4, describe the control action of three-phase brushless DC motor M in detail.
When three-phase brushless DC motor M starts (being in 101 steps), the frequency F of the triangular signal that pulse-width modulation is used is that so-called PWM carrier frequency F is set to the big value Fb (102 step) of general value Fa that uses than in the running.This measure is to be used for comparing with common running, can be rotated position probing more accurately in during judging the energising that number of poles is used.And, no matter the position of rotation of the rotor of three-phase brushless DC motor M how, all drives switching circuit 4, carry out forced commutation (103 step), promptly force to switch heterogeneous energising to three-phase brushless DC motor M.At this moment, the transistorized conduction and cut-off duty ratio of each in the switching circuit 4 keeps certain (104 step).Necessarily control starting three-phase brushless DC motor M by this forced commutation (commutation) and duty ratio.
If starting three-phase brushless DC motor M, then the pairing rotating position signal of position of rotation of the rotor of three-phase brushless DC motor M is exported from position of rotation test section 11.Detect successively from the detection of this rotating position signal by timer 22 and to play time till the detection of next rotating position signal,, detect (105 step) between the heavy loading district at heavy load test section 21 according to this time.When the end of output in 6 cycles of switching circuit 4 (106 steps be),, judge the number of poles (107 step) of three-phase brushless DC motor M according to the quantity between judging part 23 detected heavy loading districts.
Then, enter common running, from the Equipment Control portion 36 of air conditioner 30 that send with the corresponding rotary speed instruction of air conditioner load, be fed to convertor controls portion 10 (108 step).
In convertor controls portion 10, if the number of poles of judging at judging part 23 is 4 utmost points (109 steps are), then the rotating speed of target Ns based on above-mentioned rotary speed instruction directly is confirmed as rotating speed of target Ns (110 step).If the number of poles of above-mentioned judgement is 6 utmost points (109 steps not), then be set at this moment rotating speed of target Ns (111 step) based on 3/2 value of the rotating speed of target Ns of above-mentioned rotary speed instruction.
In convertor controls portion 10,, calculate the rotational speed N (112 step) of three-phase brushless DC motor M according to rotating position signal from position of rotation test section 11.And, in the case, in the calculating of the rotational speed N in the convertor controls portion 10,4 utmost points as default value, be calculated as follows: N=1/[6 * (detecting the time (second) play till next position of rotation detects from position of rotation)], perhaps N=1/ (detect the position of rotation detection of playing after 6 times till time (second)) from position of rotation].
Then, rotational speed N and the above-mentioned fixed rotating speed of target Ns that calculates compared (113 step).And, being set at PWM frequency F under the state of general value Fa (114 step), the transistorized conduction and cut-off duty ratio of each in the switching circuit 4 is controlled (115 step) according to above-mentioned comparative result.That is to say that if rotational speed N is lower than rotating speed of target Ns, then the conduction and cut-off duty ratio increases; If rotational speed N is higher than rotating speed of target Ns, then the conduction and cut-off duty ratio reduces; If rotational speed N and rotating speed of target Ns are roughly the same, then conduction and cut-off duty ratio at this moment remains unchanged.When above release, only otherwise the indication that input shuts down just turns back to 108 steps once more, carry out the rotating speed control of 108～115 steps repeatedly.
As above, judge the number of poles of three-phase brushless DC motor M according to the load change in the 1 circle rotation of three-phase brushless DC motor M, if this judged result is 4 utmost points, then directly the rotating speed of target Ns based on rotary speed instruction is used as rotating speed of target Ns, the output of switching circuit 4 is controlled; If judged result is 6 utmost points, then 3/2 of rotating speed of target Ns is worth as suitable rotating speed of target Ns, the output of switching circuit 4 is controlled.So, in convertor controls portion 10, utilize program that 4 utmost point d.c. motors use calculation procedure as actual speed, also can be all the time among the three-phase brushless DC motor M of the three-phase brushless DC motor M of 4 utmost points and 6 utmost points any be carried out suitable driving.
To the processing that the number of poles of three-phase brushless DC motor M is judged, i.e. the control of 102～107 steps is only carried out once when starting, and very short time promptly comes to an end, so, influence the temperature control of air conditioner 30 hardly.
And, in the above-described embodiments, the judgement of 4 utmost point d.c. motors and 6 utmost point d.c. motors only has been described.Because the main flow of d.c. motor is 4 utmost points and 6 utmost points, so, even only judge that 4 utmost points and 6 utmost points also can be fully practical.And,, can be applicable to that also the electric current to flowing through in each phase winding carries out the situation that calculation process is inferred position of rotation though detect position of rotation according to the induced voltage of each phase winding.
[2] below, the 2nd embodiment of the present invention is described.
In the 1st embodiment, according to the judged result of 4 utmost point d.c. motors and 6 utmost point d.c. motors, Ns proofreaies and correct to rotating speed of target.But in the 2nd embodiment, change to the method that the actual speed of motor is proofreaied and correct.At this, as shown in Figure 5, carry out the control of 201～206 steps, replace the control of 108～113 steps of the 1st embodiment.
That is to say, in convertor controls portion 10, according to the position of rotation of position of rotation test section 11, obtain the time of heterogeneous energising step mode separately, promptly detect time (so-called conduction time) t (201 step) that plays till next position of rotation detects from position of rotation.If the number of poles of judging is 4 utmost points (202 steps are), then above-mentioned t conduction time that has obtained directly is confirmed as target conduction time (203 step).If estimative number of poles is 6 utmost points (202 steps not), then above-mentioned obtained conduction time t 2/3 value redefined and be t conduction time (204 step).And, utilize the following formula that has adopted fixed target t conduction time, can obtain the rotational speed N (rps) of three-phase brushless DC motor M.
N＝1/(6×t)
Send and the corresponding rotary speed instruction of air conditioner load from the Equipment Control portion 36 of air conditioner 30, compare the rotational speed N (206 step) that goes out with corresponding rotating speed of target Ns of this rotary speed instruction and aforementioned calculation.Afterwards, be set at PWM frequency F under the state of general value Fa (114 step), come each transistorized conduction and cut-off duty ratio (115 step) in the control switch circuit 4 according to above-mentioned comparative result.
Other structures, effect is identical with the 1st embodiment with effect.Therefore, its explanation is omitted.
[3] and, the present invention is not limited only to the various embodiments described above, the implementation phase, in the scope that does not break away from its main idea, can after the distressed structure key element, be implemented.And, utilize the appropriate combination of disclosed a plurality of structural elements in the various embodiments described above, can form various inventions.Also can from the entire infrastructure key element shown in each embodiment, remove several structural elements.
