In a motor control apparatus having a phase voltage detecting circuit, there exists the loss of the phase voltage detecting circuit during the control process. Therefore, the invention aims at providing a motor control device capable of handling the changes of DC voltage for various motors having small storage capacity and high efficiency. To solve the problem, a mode having low loss of the phase voltage detecting circuit and the low switch loss of the inverter is selected according to the modulation rate. Moreover, when the modulation rate is small, a down 120 DEG C fixed two-phase modulation is carried out.

Description
Technical field
The present invention relates to have phase voltage testing circuit, carry out the high efficiency control of the control device of electric motor of 180 degree energising controls based on resistance.
Background technology
For example, under the situation of the outdoor fan that is provided with in the off-premises station that drives at air conditioner, before passing through the inverter startup motor, fan rotates (idle running) arbitrarily owing to wind sometimes.At this moment; When the circuit through having used a shunt resistance with no velocity pick-up vector control (senseless vector controlling) when carrying out the driving of motor; Switch element at inverter is not switched under the state of shutoff (ON/OFF), can't confirm because what kind of electric current the electric current that the induced voltage of motor produces is.Its reason is, the inferring of this position of magnetic pole is that logically to derive the current electric current that flows through shunt resistance through the timing of carrying out switch (switching) according to inverter be that what kind of method of current is carried out.
Therefore; In patent documentation 1, proposed outside the no velocity pick-up vector control of using a shunt resistance to carry out; The unit of the phase voltage that detects motor is set, the control device of the motor of the direction of rotation of the rotor of detection motor, rotary speed, position of magnetic pole before passing through the switch drive motor of inverter.
According to patent documentation 1; Append at fan because wind etc. disturb the circuit that detects the induced voltage of motor under the situation of rotating arbitrarily; Detection rotor position of magnetic pole, rotary speed and direction of rotation before inverter carries out switch; Thus, even when starting, have interference also can be controlled to be the rotary speed of hope.
The PWM control of general three-phase alternating-current motor is three-phase modulations; But the 110th, 111,125 page of the books " semiconductor power translation circuit " of electric association of the civic organization in March, 1987 distribution etc. separate to be right and put down in writing a kind of bi-phase modulated; It utilizes motor current not pass through the fact of voltage between phases decision through the phase voltage decision; Through while guarantee voltage between phases each expected time of arrival the chien shih inverter switch element connect (ON) all the time; Can make each electrical degree of each phase voltage be fixed as high-order power level or low level power level successively, reduce the switching losses of inverter with π/3 (60 degree).Below, call immobile phase 60 degree switching modes to above-mentioned bi-phase modulated mode.Fig. 2 representes the voltage waveform of three-phase modulations mode, and Fig. 3 representes the voltage waveform of immobile phase 60 degree switching modes.
In addition; Proposed through following patent documentation 2,3; Make each electrical degree be fixed as the switching losses that high-order power level or low level power level reduce inverter successively with 2 π/3 (120 degree); Under the little situation of the amplitude of phase voltage, stop this bi-phase modulated mode, motor is applied three-phase voltage.Below; Call immobile phase 120 degree switching modes to above-mentioned bi-phase modulated mode; To call the mode that immobile phase is fixed on the high potential of direct voltage immobile phase 120 degree switching modes especially, will call immobile phase 120 degree switching modes down to the mode that immobile phase is fixed on the electronegative potential of direct voltage.Fig. 4, Fig. 5 represent the voltage in three phases waveform of each modulation system.
As patent documentation 1, under the situation of the control mode of using resistance as the means of the phase voltage that detects motor, when when in operation usually, producing phase voltage, detect in phase voltage and to flow through electric current in the resistance, lose.
Detect the loss of resistance generation, the switching losses of inverter through phase voltage, change according to modulation system and modulation rate.
The technology of patent documentation 1 does not change with modulation system because consider loss, the switching losses of phase voltage detection resistance, so can't high-efficiency operation.
The technology of patent documentation 2 is that purpose changes modulation system with the maximum that reduces leakage current, does not consider that the loss of phase voltage testing circuit, switching losses change with modulation system, so can't high-efficiency operation.And because change modulation system, so can't high-efficiency operation under the situation of the dc voltage change of inverter according to rotating speed.
The technology of patent documentation 3 is that purpose changes modulation system to reduce loss; But because do not consider the loss of phase voltage testing circuit; So under the situation of having selected immobile phase 120 degree switching modes, do not show immobile phase 120 degree switching modes clearly and still descend immobile phase 120 degree switching modes.And, because change modulation system, so can't high-efficiency operation under the situation of the dc voltage change of inverter according to rotating speed and torque or iq electric current and id electric current.And, because determine the switching point of modulation system, need big memory capacity with two-dimensional coordinate.

Lifting shunt resistance as current detecting unit is example, but replaces shunt resistance and use current sensor also can realize above-mentioned startup method.
Common control, particularly motor apply the computing of voltage, for example use with TOHKEMY 2002-272194 communique in the same method of method put down in writing carry out.In addition, beyond said method, also can use the three-phase or two of motor current to calculate the three-phase alternating current command voltage mutually.
Rotor is described owing to disturb to wait and is rotated arbitrarily under the situation of (idle running) direction of rotation and the method for rotating speed when detecting interference through phase voltage detector 6.Threephase motor 3, preceding at inverter 2 switches (switching), motor rotates owing to disturbing, and thus, produces induced voltage Vu, Vv, Vw in each phase.When detecting these induced voltages with phase voltage detector 6 and calculating voltage between lines, because become sine wave, so rotating speed, direction of rotation, phase place that can calculating motor.
The computational methods of modulation rate arithmetic unit 403 then, are described.Modulation rate is the signal wave amplitude and the ratio of the amplitude of carrier wave, so in the PWM of inverter control, signal wave becomes the sine wave that on motor, applies, and carrier wave to become with 1/2 of direct voltage be the square wave of amplitude.Therefore, when the sinusoidal wave amplitude that on motor, applies as Vs

By phase voltage detect the loss that resistance causes, the switching losses of inverter changes according to modulation system and modulation rate.When Fig. 6 representes that direct voltage is 280V, the modulation rate in each modulation system and the relation of loss.The relation of loss is last 120 ° of fixing fixing fixing orders of bi-phase modulated of 120 ° of bi-phase modulated＞three-phase modulations＞following of 60 ° of bi-phase modulated＞up and down.In addition, carrying out up and down 60 ° fixedly under the situation of bi-phase modulated, three-phase modulations, the influence of modulation rate is little in the loss.Carrying out following 120 ° fixedly under the situation of bi-phase modulated, during low modulation rate loss little, the high more loss during more near three-phase modulations of modulation rate.On carrying out 120 ° fixedly under the situation of bi-phase modulated, during low modulation rate loss big, the high more loss during more near three-phase modulations of modulation rate.
Switching losses also changes according to modulation system.This depends on when electric current is big, whether to carry out switch.Relatively when three-phase modulations and bi-phase modulated, because the switch number of three-phase modulations is 3/2 of a bi-phase modulated, and switch is many under the big situation of electric current, so the loss of three-phase modulations is big.Then; Even in bi-phase modulated, when relatively 120 ° of fixedly bi-phase modulated and 60 ° fixedly during bi-phase modulated up and down, hour much at one in modulation rate; When modulation rate is big electric current big, carry out switch, below the institute 120 ° fixedly bi-phase modulated than up and down 60 ° fixedly the bi-phase modulated loss become big.
Fig. 7 representes to comprise phase voltage and detects resistance and the circuit loss of SW loss and the relation of modulation rate.When modulation rate is high, in the example of Fig. 7, modulation rate be 0.8 o'clock from following 120 ° fixedly bi-phase modulated switch to up and down 60 ° fixedly during bi-phase modulated, can realize high-efficiency operation.
The modulation rate of switching, the relation of size that detects the loss of resistance according to the size and the phase voltage of the loss of inverter circuit decides, be preferably in 0.6～0.9 between switching.
