正弦波絶対値部分変調瞬時値制御昇圧チョッパを用いたデュアルモード正弦波インバータ

抄録

This paper presents a novel system topology of high efficiency single-phase sinewave inverter, which is composed of partial sinewave boost chopper circuit in the first power processing stage and partial sinewave full-bridge inverter in the second power processing stage operated by sinewave modulated time-sharing control scheme. Its unique operating principle of two stage power processing stage with dual mode time-sharing sinewave modulation scheme is basically described and evaluated on the basis of the computer simulation and experimental considerations.
