摘　　要：三电平逆变器在许多工业应用领域得到了广泛的应用。首先分析了二极管钳位式三相三电平逆变器的工作原理;建立了三种开关状态与输出电平数之间的关系式;对开关状态进行函数化处理,使得开关状态的处理更为方便、简单。具体分析了各开关管驱动信号的产生方法;为验证分析的正确性,借助Matlab仿真平台,进行了仿真研究。Three-level inverter has been widely applied in many industrial applications. This paper introduces the operation principle of Diode-clamped three-phase three-level inverter. Establish the connection between three kinds of switch state and the number of output levels. The function is used to indicate the switch state making the treatment of the switch state more convenient and simple. Analysis the switch drive signal generation method. To verify the correctness of the analysis,with the simulation platform of Matlab,conducted a simulation study.
