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

Glossary
Process station:
This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant
configuration and non-redundant configuration.
AC800F :
This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2
AC800F controller.
Rack mounted process station:
This term is used to describe a rack-mounted type of process station. A redundant process station contains 2 rack-mounted CPUs.
This term is used to describe a single, non-redundant process station.
In the investment of modern automation system, due to the hardware equipment department
It only takes up less cost in the whole system, then write engineering applications
The cost of software becomes increasingly important. Generally speaking, a self
The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
