中文摘要

本文综述了阻抗源网络在直流、交流及交交变换中的应用。阻抗源拓扑旨在克服传统电压源和电流源逆变器在升降压能力、可靠性及死区时间等方面的局限性,为电力电子变换器提供了更灵活的拓扑选择。

English Abstract

Impedance networks cover the entire of electric power conversion from dc (converter, rectifier), ac (inverter), to phase and frequency conversion (ac–ac) in a wide range of applications. Various converter topologies have been reported in the literature to overcome the limitations and problems of the traditional voltage source, current source as well as various classical buck–boost, unidirectional,...
