单相电容电机变频调速器的逆变器结构

The Inverter Form of Varying Frequency and Speed Regulation for Single-phase Capacitance Motor

本文探讨了实现单相电容电机变频调速逆变器主电路的形式。根据这种电机结构及运行特点，文中提出了四种不同的主电路，并分析比较了各自的优点和不足。最后介绍了在实验室建立的逆变器─电机系统，以及电机变频调速的运行结果。

This paper studies the main power circuit of inverter to obtain the result of varying frequency and speedregulation for single-phase capacitor motor. Based on the features of this kind of motor,four different main power circuits are presented and the disadvantages and advantages for each are analysised and compared. This paper also introduces the inverter-motor system established in the laboratory and the running result.
