| Abstract | ||||
| Unbalance in the operation of AC/DC converters gives rise to abnormal or uncharacteristic current harmonics, in addition to the characteristic harmonics in the supply current waveforms. This paper concentrates on the analysis of uncharacteristic harmonics caused by unbalanced AC supply voltages. Attention is given to modified converter operation which uses thyristors connected to tapping points on the secondary windings of the transformer. Control of by-pass thyristor for reducing abnormal harmonic generation are discusses, and some experimental results supporting the theoretical calculations are also included. | ||||
