摘　　要：矩阵变换器是一种新型交交变频电源 ,因结构简单和性能优越正吸引越来越多的国内外学者深入研究 .对制约其应用的关键技术之一的双向开关换流问题进行了深入分析 ,通过引入换流死区和辅助开关的概念 ,提出了一种基于电压检测的新型换流策略 .The matrix converter,a new kind of AC AC power supplies, has attracted considerable attention in recent years because of its simple structure and powerful controllability. The commutation problem, which is one of the major causes to hamper the applications of matrix converters,is studied.A novel commutation technique based on the detection of voltage is proposed and the simulation results show the effectiveness of the method.
