2-2 SD3100 Power Modules
2.1 Mechanical Overview
The SD3100 Power Module is composed of the basic components shown in figure 2.1.
These components consist of:
• Control components that provide the interface to the AutoMax Distributed Power
System and control for the Power Module, and
• Power components that convert AC line power to DC power for the motor.
2.1.1 Control Components
The control components are contained in the regulator assembly, along with the Field
Power Module. The regulator assembly is mounted in the lower compartment of the
Power Module’s Disconnect Bay.
The PMI rack contains the four modules that make up the PMI Regulator: the PMI’s
Power Supply, Processor module, Resolver and Drive I/O module, and DC Power
Technology module. The PMI Processor executes the control algorithm and
communicates with the AutoMax processor via its fiber-optic ports. The Resolver and
Drive I/O module provides the interface for speed feedback and control signals. The
DC Power Technology module provides the armature feedback, armature forward gate
control, armature reverse gate control (regenerative models only), and the field
feedback and gate control signals for the Field Power Module.
