3상 비대칭 정류회로의 PAM 방식을 이용한 고주파 저감법
Reducing Harmonics of 3-Phase Asymmctic Recnher Current using a PAM mcthod
- 발행 : 1995.10.01
초록
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.
