• Bridge Feedback: Monitors DC link voltage, output currents, field voltage, and temperature.

Relay Control

• Simplex: Controls de-excitation relay (K41).
• Redundant Systems: Manages charging relay (K3) for enhanced reliability.

Connectivity

• Form Factor: Single-slot, double-height (6U).
• Connectors: Seven connectors for interfacing.
• Backplane: P1 and P2 connectors for integration.

Board Identification

• Board ID Device: Embedded with serial number, type, and revision data for identification and communication with M1/M2 control.

Power & Isolation

• Control Circuits: Powered by Exciter Power Supply Module (EPSM).
• Dynamic Discharge Power: Powered by EPSM and redundant DC link source for reliability.
• Isolation: Robust isolation between control power and IGBT bridge.

Power Supply & Circuits

• Dynamic Discharge Converter: Utilizes transformer secondary windings for power conversion.
• Isolated Power Supplies: Six isolated power supplies enhance reliability and isolation.
