control cabinet for the control, communication, and I/O boards
auxiliary cabinet for field flashing and protection circuits such as de-excitation
and shaft voltage suppression
power conversion cabinet for the power SCR cells, cooling fans, dc contactors,
and ac disconnect
The exciter's power converter consists of bridge rectifiers, resistor/capacitor filter
