【摘要】 三电平逆变器在中压大功率场合得到了广泛的应用。研究了二极管箝位型三电平逆变器的结构及工作原理;提出了一种基于数字信号处理器TMS320LF2407的空间矢量调制控制算法;分析了中点电位的平衡问题,并提出了相应的解决方法。通过实验论证了该方案的可行性。
【Abstract】 Three-level inverters were widely used in medium-voltage high-power domain. This paper describes the basic structure and control principles of the three-level NPC inverters, introduces a space vector PWM modulation strategy based on TMS320LF2407 DSP,analyzes the problem of Neutral-Point balance and also presents the solution for it.Experimental result demonstrate the feasibility of the mentioned scheme.
