Abstract

Unbalance in the operation of high-voltage dc convertors gives rise to unusual or uncharacteristic harmonics in the ac waveform not expected from the existing theory relating to balanced operation. Analysis of the effect of unbalances in the altemating voltages and the valve firing angles is provided together with selected characteristics illustrating the variations in the harmonics with unbalance as determined by a comprehensive digital computer program. Six-pulse and 12-pulse operation is considered.
