Abstract

In this paper, we persents a new PAM method without the input transformer for reducing harmonics in input AC line currents of converter. This system can reduce the harmonics like conventional 12-pulse converter. the dual bridge circuits are controlled with the shifted firing angle and connected 2 tap interphase reactor. the input current using 2 tap changing on interphase reactor is controlled with the different two values in order to make the input current waveform 12 pulses. The chracteristics of this system were confirmed through the computer simulation and the experiments.
