Abstract: This paper deals with the 12 pulse convertor for rectification process. Three-phase thyristor rectifiers have been used in industries for obtaining a variable dc voltage, but the lower order harmonics are the major problem present in the input currents of these systems.12- pulse convertor configuration is very useful in high power applications, but the (12m ± 1)th (m: integer) harmonics are still presents in the system. Thus this paper proposes the further reduction in harmonics using auxiliary supply and analyses the performance of a dc motor supplied by the 12 pulse convertor with auxiliary voltage supply assisted.
Keywords: AC–DC power conversion, power conversion harmonics, power electronics, thyristor applications, thyristor converters.
