ARRANGEMENT FOR SYNCHRONIZING STATIC THYRISTOR TRANSVERTERS FOR SUPPLYING THREE-PHASE MOTORS

摘要

An arrangement for synchronizing two static converters supplying three phase motors so that one converter may be taken off the line and the other put on the line without disturbance in which the firing pulses for the thyristors in the converters and generated in the converter control unit are used to make phase and frequency comparisons in order to initiate switching.
