SINAMICS GM150 in IGCT Tandem version
The SINAMICS GM150 series has been extended by two water-cooled types in
IGCT tandem version.
5.1
概述
随着Sinamics GM150的功率范围的扩展，驱动器
applications can be equipped with up to 23 MW for a motor voltage of 6.6 kV.
这是通过使用短小l-proven SINAMICS GM150 IGCT medium-voltage
驱动器，每个驱动器的输出电压为3.3 kV，相位偏移约为。180°
feeding an open 6.6 kV motor winding system.
驱动系统包括两个三级逆变器，其表现就像五级
转换器和17电压水平连接到电动机绕组会产生
几乎正弦电流电流。

Block diagram tandem configuration
In the tandem configuration, two basic converter units feed a motor with an open
winding system, so that the two converters with nominal voltage 3.3 kV each result
在6.6 kV的绝缘电压中。因此，串联版本包括不同的
components than the converter units in a basic or parallel circuit. The motor wiring
cannot be changed in the tandem configuration.
