摘要:变频器主要组成是电力电子器件和微电子器件,其主电路由电力电子器件组成,它的输入输出侧的电压、电流含有丰富的谐波,容易对电网、负载和其他电气电子设备产生干扰;而变频器的控制电路是以计算机芯片为核心组成的,其工作电压、电流极小,极易受到外界干扰造成失控.通过变频器对外界干扰及外部对变频器干扰机理的研究,提出确保变频器应用系统在实际工作中安全可靠地运行即实现电磁兼容的方法.

Realization of electromagnetic compatibility in the applied system of inverter

Abstract:Inverter is mainly composed of power electronic devices and microelectronic devices.The main circuit of inverter is made of electric power and electronic devices, which has lots of harmonic waves in voltage and current on the port of input and output.It is easy to bring the interferences to the electric network, load, and other equipments of electronics and electricity.The inverter is controlled by computer chips.It working voltage and current are very small, and is easily out of control because of the external interferences.Through the study of inverter interferencing and external reaction, the assurance of safe and reliable operation in inverter application system is put forward in practical work, which, namely the electromagnetic compatibility.
