摘要：A control system for an A.C. motor which is connected to the output terminalsof a thyristor inverter, a capacitor is connected between the D. C. input terminals of thethyristor inverter, and the respective thyristors constituting the inverter are extinguishedby self commutation due to an oscillating current produced by the capacitance of thecapacitor and the reactance component of the armature coils of the A. C. motorconnected to the A.C. output terminals of the thyristor inverter, and a current in thewaveform of pulses produced by electric oscillation is delivered in a predeterminedphase sequence to the armature coils of the A.C. motor.
