IGBT 供电单元包括一个 IGBT供电模块,一个进线滤波器 (LCL 滤波器),交流 和直流熔断器及其他可选设备。 IGBT 供电模块将输入的三相交流电变为直流电向传动单元中间直流回路供电。进而，中间直流回路向驱动电机的逆变器供电。中间直流回路可以只接入一个逆变器（单传动），也可以接入多个逆变器（多传动）。进线滤波器用来抑制交流电压畸变和电流谐波。
IGBT 供电单元是一个四象限脉冲整流器, 四象限脉冲整流器可以向中间直流回路供电，也可以将中间直流回路的能量回馈回电网。一般情况下，四象限脉冲整流器将中间直流回路的电压控制在输入线电压峰值以下。通过对一个参数进行设置，可以使中间直流电路的电压更高。为了满足控制需要，对两个线电流和中间直流回路电压进行了测量。

Configuration software is a kind of special software used for data acquisition and process control in industrial automation industry. It is a platform software used for monitoring layer of automatic control system. Automation engineers are accustomed to using configuration software to develop monitoring platforms.
With the development of the Internet of Things, industrial automation platforms need to realize remote monitoring of mobile phone apps and web pages. Traditional configuration software can only be used for LAN systems. If mobile phone apps and network monitoring are needed, network engineers used to cooperate with customization, which takes a long time and costs a lot. With the increase of demand, industrial control automation industry has developed a mature cloud configuration system, in accordance with the habits of industrial control automation engineers, can develop a good monitoring platform system, directly into the network platform and mobile APP monitoring. Based on the mature cloud configuration webgui of Guangzhou Giant Electronics as the development basis, this paper completely introduces how automatic control engineers do mobile phone APP to remotely monitor PLC.
I. PLC system data acquisition and communication
The traditional configuration and PLC communication adopt Ethernet, 485, 422, 232 and other communication methods, which need to be connected by wire. Because the position of mobile phone or network terminal is not fixed, so the traditional data acquisition method is not suitable, so the PLC
