    • An angular position detector for generating trains of A- and B-phase pulses which are 90.degree. out of phase with each other and a C-phase pulse per rotation are mounted on a permanent-magnet synchronous motor such that a magnetic pole origin of permanent magnets and a position where the C-phase pulse is generated agree with each other. After a power supply voltage is applied and in an initial stage before the permanent-magnet synchronous motor is operated normally, a motor control apparatus operates a current control loop with an alternating current command having a constant amplitude and a low frequency to supply an alternating current having a low frequency to the permanent-magnet synchronous motor for thereby rotating the rotor of the permanent-magnet synchronous motor from a stop at a low speed. The motor control apparatus then detects arrival at a magnetic pole reference when a C-phase pulse is detected, and detects an angular displacement of the magnetic poles of the rotor using counts of the A- and B-phase pulses counted in synchronism with the rotation of the rotor after the C-phase pulse is detected.

    • A power converting apparatus and a power converting method for driving a high voltage AC motor at a variable speed. Conventional invertor systems cannot solve technical subjects such as energy conservation, resource conservation, miniaturization, efficiency promotion and voltage and current waveform distortion suppression for improvement in environment needed by the market, and cannot solve another technical subject of improvement in redundancy such that, upon failure, operation is performed with a normal part. In the present invention, a power converting apparatus of a multiple three-phase pulse width modulation cycloconverter system for driving a high voltage AC motor at a variable speed is used, and bidirectional semiconductor switches are controlled so that voltages of AC outputs to be outputted to single-phase AC terminals of three-phase/single-phase pulse width modulation cycloconverters may have a same phase in each of units but electric angles of basic wave voltage phases may be different by 120 degrees from each other among the three units to drive a high voltage AC motor. If one of the cycloconverters fails, then the single-phase AC terminals of the failed cycloconverter are short-circuited and three sets of switches each consisting of two bidirectional semiconductor switches connected to three-phase AC terminals of the cycloconverters of the other two units in the same group as the failed cycloconverter are successively rendered conducting one by one set at equal time intervals to short-circuit the three sets of the bidirectional semiconductor switches to drive the high voltage AC motor at a variable speed.
