摘要：A harmonic blocking converter system for converting power between an ACsource and a DC source includes a harmonic blocking transformer and a converter whichgenerates undesirable harmonic currents including fifth and seventh harmonic
components. The harmonic blocking transformer includes a polyphase main transformerand a harmonic blocker coupled with wye and delta secondary windings of the maintransformer, so as to substantially block passage of the fifth and seventh harmoniccurrents to the AC source. A waveform enhancer may couple the harmonic blockingtransformer with the converter. The converter may be constructed for 2- level operation,or, with the addition of auxiliary diodes, for 3- level operation. Such a harmonic blockingtransformer and a method of blocking undesirable harmonic currents are also provided.
