摘要： 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.

摘要： A bridge-type power converter has, in each phase, a inductor (L.sub.1) connected between a connection point of said two switching elements (Q.sub.1, Q.sub.2) and an output terminal; capacitors (C.sub.1, C.sub.2) connected between the output terminal and a positive or negative side of a d.c. bus for changing an output voltage along a curve determined by a phenomenon of resonance with the reactor (L.sub.1) when the semiconductors switching elements (Q.sub.1, Q.sub.2) operate, causing abrupt changes of a voltage at the connection point; diodes (D.sub.3, D.sub.4) for changing a current path at a time when the resonance goes approximately one quarter of period to thereby stop the resonance; and constant voltage diodes (ZD.sub.1, ZD.sub.2) for absorbing the energy stored in the inductor (L.sub.1) during the resonance.
