Converter Cabinet

The converter cabinet contains three rectifier modules and three inverter
modules.

Figure on page 46

shows a 2300-volt converter with an AFE Rectifier.

Isolated Gate Driver Power Supplies (IGDPS) are available on the cabinet’s right
side sheet.

Thermal sensors are available on the top module of the inverter and rectifier. The
exact location depends on the drive configuration. These sensors connect to
temperature feedback boards that return signals to the drive control.
