Under-zero current switching (UCS) was examined through the high power back to back (BTB) experiment using a 90kW 3-phase interleaved chopper. The proposed Snubber Assisted Zero voltage and Zero current transition (SAZZ) topology obtained the highest efficiency of 97.42% at 30kW, 1.82% higher than hard SW (95.6%), and the highest efficiency over the entire power region. This was verified through the load test and loss breakdown up to 30kW per phase, and its performance for the under-zero current switching behavior was confirmed.本誌: IEEJ Journal of Industry Applications Vol.4 No.1 （2015） Special Issue on Motion Control and its Related Technologies本誌掲載ページ: 31-39 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/4/1/4_31/_article/-char/ja/ Show more
