고속전철 보조전원장치용 4병렬 IGBT PWM 컨버터에 관한 연구
A Study on 4 Parallel IGBT PWM Converter for High Speed Train Auxiliary Block
초록
Power factor and harmonics are increasingly important for high speed train auxiliary block. This paper presents experimental results of the power factor and harmonic performance of four parallel PWM converter circuits under various supply and load conditions. For reducing harmonics the harmonic content is eliminated by the phase shift between four converters switching phase. Experimental results show the usefulness of the proposed method and applicability to PWM converter in auxiliary block of high speed train.
