“…For the new commutation circuits, a net commutating voltage E, is defined as a voltage difference between E, (auxiliary DC source) and the supply voltages involved in the commutation (refer to Eqs. ( 4 ), (6) and (7) ). E, contributes to the energy transfer of the source inductances and hence, it has direct influence upon the overlapping time to and so the commutation time tc.…”

The presence of the AC source inductance often makes the forced commutation scheme difficult to apply to AC/DC and AC/AC thyristor converters. This paper proposes a novel forced commutation method based on the voltage injection technique which handles the inductive energy in the same manner as achieved with the line commutation. A comparative analysis with the conventional capacitor-type commutation shows that the new method is capable of commutating higher load current with less thyristor voltage, commutation time and commutation power. A simple but effective pulse-width controlled AC/DC converter with the new method is also presented with experimental results.
