准Z源逆变器中磁性元件的集成设计
|
摘要
准Z源逆变器是一种新型的逆变器,解决了传统逆变器需要额外升压电路的不足,能够实现单级升压逆变功能。但是准Z源逆变器的无源网络需要两个电感,会给变换器带来体积大重量大的问题。针对此问题提出一种磁集成准Z源逆变器,由于将两个独立的电感绕制在一副磁芯上,因此磁性元件体积重量得以减小。并通过实验验证了理论分析的正确性。
The quasi-Z source inverter is a new type of inverter that solves the inadequacies of the need for additional boost circuits in conventional inverters and enables a single-stage step-up inverter function. However,the passive network of a quasi-Z source inverter requires two inductors,which will bring about a large volume and weight problem to the converter. A magnetic integrated quasi-Z source inverter is proposed for this problem. Since two independent inductors are wound on a magnetic core,the volume and weight of the magnetic element can be reduced. Through experiments,the correctness of the theoretical analysis was verified.
