    摘要： A motor control device for an AC motor driven by a power converter with a maximum output frequency more than 500 Hz has a digital arithmetic unit which performs current-feed back control of the AC motor up to a maximum output frequency of the power converter, and outputs an AC voltage command to the power converter. The digital arithmetic unit includes a voltage control signal calculating unit for calculating a vector sum of the d-axis current deviation from a first subtracting unit and the q-axis current deviation from a second subtracting unit based on the d-axis and q-axis phases from a phase calculating unit as well as for calculating a d-axis voltage control signal and a q-axis voltage control signal according to the calculated vector sum, and performs current integration control for the d-axis and q-axis using the calculated vector sum as an input value. The AC voltage command is calculated based on the d-axis voltage control signal and the q-axis voltage control signals.

    摘要： A synchronous motor control system includes a synchronous motor 1, an inverter 3 and a controller 4 wherein a current differential detecting unit 13 detects a variation of a motor current when the three phases of the motor 1 is short circuited by the inverter 3, namely at the moment when a carrier wave in a PWM signal generator 9 assumes maximum or minimum value, in a calculating unit 14 a phase &ggr; from &agr; axis of a stationary coordinate system to a three phase short circuited current differential vector is calculated, a phase &dgr; is estimated from d axis to the three phase short circuited current differential vector by making use of d axis current id and q axis current iq on d-q axes coordinate system in the controller 4, thereafter the magnetic pole position &thgr; with respect to &agr; axis is calculated from the phases &ggr; and &dgr;, based on thus calculated magnetic pole position &thgr;, d-q axes control units 11, 7 and 8 are constituted to control the synchronous motor, thereby a highly reliable control system for the motor which permits a detection of the magnetic pole position without affecting a state of applied voltage thereto while performing a usual PWM control with a low cost controller.

    摘要： An inverter system providing both an improvement in the voltage utilization factor and a reduction in the switching loss uses a two-phase switching method. In the inverter system, an .alpha.-axis voltage command value; v.sub..alpha.r and a .beta.-axis voltage command value v.sub..beta.r are input to a stop phase selection means. Six sections are judged based on the values v.sub..alpha.r and v.sub..beta.r to select phases for which it is allowable to stop pulse width modulation control in a two-phase switching method. Then, a phase having the largest absolute value of current is selected among the phases for which it is allowable to stop pulse width modulation control using a U-phase current i.sub.u and a V-phase current i.sub.v. This information is a control mode S. Based on these, two-phase switching calculations are performed by a dead-time compensation calculation means and a pulse width modulation generating means. By doing so, the switching loss can be reduced.
