近年来,三电平逆变器在高压、大容量的场合得到了越来越广泛的应用。在其浩如烟海的控制策略中,SVPWM算法控制策略具有调制比大、能够优化输出的电压波形,而且母线电压利用率高,此外容易数字实现等优点。本文首先对三电平逆变器技术目前的发展情况做出了综述,分析SVPWM控制策略以及它的优缺点。采用Simulink进行仿真分析,实现对三电平逆变器的SVPWM控制算法的仿真,观察系统的输出波形,分析波形,并进行比较,验证了算法的可行性。
In recent years, the three level inverter have been more and more widely used in high voltage, large capacity occasions. In the control strategy of the voluminous, the SVPWM algorithm has many advantages, such as large modulation ratio, optimized output voltage waveform, high bus voltage utilization, easy digital implementation, and so on. This paper reviews the current development situation of phase inverter technology, and analyzes the SVPWM control strategy and its advantages and disadvantages. By Simulation analysis using Simulink,this paper realizes the simulation of SVPWM control algorithm for three phase inverter, observes, analyzes and compares the output waveform of system, and then verifies the feasibility of the algorithm.
