适用于 ACS880 传动中使用的 ACS880 IGBT 供电控制程序（AISLX v2.6x 或更高版本）和 ACS880 IGBT 两象限供电控制程序（ALHLX v2.6x 或更高版本）传动. 本手册包括两个版本的控制程序：使用在再生传动上面的IGBT 供电控制程序和使用在低谐波传动（非再生传动）上面的IGBT 供电控制程序。再生传动有带IGBT 供电单元的ACS880多传动， ACS880 -14 和ACS880 -17。低谐波传动有ACS880 -34 和ACS880 -37。 适用于 ACS880-904 再生整流器模块，该模块用于用户定义的柜体安装。
再生整流器单元 (RRU) 包含一个或多个整流器模块 (nxR8i) 和 L 滤波器。每个 R8i 模块由六个 IGBT 组件和以反并行方式连接的六个二极管构成。在电动模式下，电流从交流电源开始，经过二极管流入直流母线。在再生模式下，电流从直流母线开始，经过 IGBT 流入供电网络。
再生整流器单元的 IGBT 导通开关，与 6 脉冲二极管供电单元相比，在每次网络电压半周期期间仅导通一次。这样减少了开关损耗，使功率模块具有更高的功率额定值。由于 IGBT 可以在任何时候关断，因此即使在再生模式下的供电网络故障期间，RRU（与晶闸管桥不同）也非常可靠。
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.
