摘要
介绍了级联型多电平变频器的主电路拓扑及其工作原理,并阐述了载波相移脉宽调制技术的基本原理。设计了一台级联型多电平变频器样机,试验波形验证理论的可行性。该变频器采用模块化结构,发展前景好。
Main circuit structure and theory of cascade muhilevel high voltage inverter were introduced. The basic theory of the carrier phase shifteds PWM technology was mentioned. The sample of cascade muhilevel high volt- age inverter was made, and the experiment output wave validated the feasibility of theory. The inverter used model structure, and had great development foreground.
