适用于在用户定义柜体安装中使用的 ACS880-304 +A003 二极管供电模块。
介绍二极管供电单元的工作方式，以及二极管供电单元的硬件。这些信息适用于ACS880-304 +A003 二极管供电模块。
二极管供电单元的核心是六脉二极管桥。该桥可将三相交流电整流为直流电，以用于传动的中间直流回路。中间直流回路为运行电机的逆变器供电。可将一个逆变器单元（单传动）或多个逆变器单元（多传动）连接到中间电路。交流电抗器可使传动供电电网中的电流波形以及直流回路中的电压变得平滑。
ACS880-304 +A003 供电模块中的整流器桥不受控制：它在上电时无法控制直流回路电压，也不能限制直流回路电容器的充电电流。因此，只能用于具有内部充电电路的逆变器，或者必须配备具有独立外部充电电路的供电单元。控制程序允许使用外部充电电路，但 ABB 不提供用于其连接的组件。ABB 逆变器框架尺寸 R1…R4i 标配内部充电电路。R6i…R7i 的内部充电电路作为选件(+F272)。
