资料介绍

应用PWM变频器中产生的共模电压对系统运行的可靠性会造成影响。本文对电压源PWM变频器出现的共模电压和负效应产生机理进行研究,从而得知产生共模电压的原因和抑制方法,也得知变频器输出的负面影响主要来源是共模电压。本文主要围绕PWM变频器展开讨论,首先对其共模电压和相应的抑制技术进行分析,最后通过实验及实验结果,对共模电压系统负面效应产生的根源进行分析。

The application of the common mode voltage generated in the PWM inverter will affect the reliability of the system operation. In this paper, the common mode voltage and negative effect generation mechanism of voltage source PWM inverter are studied to know the cause and suppression method of common mode voltage. It is also known that the main source of negative feedback of inverter output is common mode voltage. This paper focuses on the discussion of PWM inverters. Firstly, the common mode voltage and corresponding suppression techniques are analyzed. Finally, the root causes of the negative effects of the common mode voltage system are analyzed through experiments and experimental results.
