AC/DC Power Supply
The load demands on the AC/DC converters are the DC/DC converter and up
to six IGDPS modules. The DC/DC is a fixed load; however, the quantity of
IGDPS modules will vary depending upon the drive configuration.
The AC/DC power supply accepts single phase voltage and produces a regulated
56V DC output for the DC/DC power supply and the HV IGDPS modules that
power the SGCTs. The input and output voltages are monitored and fail signals
are annunciated upon either voltage going below a pre-set level.
