Abstract
A power system plant includes a backplane arrangement including a primary and secondary bus to which intermediate power processing modules are selectively connected to the input and output power control and monitors of the plant. The backplane connections are controlled by the plug-in power processing modules. , the resulting connections are unique to the type of plug-in module placeed placed on an input shelf (i.e. rectifier or converter plug-in module) and determine how the plant is to operated. The connections of these plug-in modules to the backplane connector are such that the plug-in module is designed to have its connectors connect to either primary or secondary referenced control signals. The connectors of the backplane accept both type of plug-in modules so that any plug-in module inserted is automatically connected to respond to the appropriate primary or secondary referenced control signals.
