摘要： An inverter apparatus for converting a DC power converted from an input AC power to an output AC power of a variable frequency and a variable electric power to drive an induction motor at a variable speed. The inverter apparatus includes a rectifying unit, a filter capacitor, an inverter unit having an input connected across the filter capacitor, an input current detector and a gate circuitry for driving the inverter unit. An excitation current detection unit detects an excitation current of the induction motor from an output signal of the input current detector, a gate signal for driving the gate circuitry and a reference phase command. A setting unit sets a limitation level of the excitation current, a torque boost voltage command unit produces a torque boost voltage command, and a torque boost voltage compensation unit changes the torque boost voltage command so that the detected excitation current value is smaller than or equal to the limitation level.

摘要： An inverter corrects an output voltage in accordance with the magnitude of output voltage error due to a dead time and an ON-state voltage drop in power elements so as to energize an AC motor in a manner of single phase alternating current excitation, by calculating an active component of current Iq and a reactive component of current Id from the phase .theta. of an excitation voltage vector and a detected instantaneous current value iu, and by measuring characteristic constants of the motor, including a combined resistance (r.sub.1 +r.sub.2) and a combined leakage inductance (l.sub.1 +l.sub.2), from an excitation voltage command value Vc.sub.1, Id and Iq. The measured values are used as the control constants for a speed sensorless vector control. Further, the resistances r.sub.1, r.sub.2, and a self-inductance L.sub.1, which are control constants, can be obtained based on the component in a primary voltage vector direction of a primary current vector Iq' and the component .pi./2 delayed from the primary voltage vector direction of the primary current vector Id'. In this way, the characteristic constants can be accurately measured without any inverter output voltage sensor.
