GE DS200IIBDG1A IGBT Gate Driver Board for Mark V

The GE DS200IIBDG1A IGBT Gate Driver Board for Mark V is the IGBT gate-driver board of the GE Speedtronic™ Mark V DS200 board family, used in GE AC2000 / AC2000I drive systems. It provides the gate drive and isolation stage between the drive control logic and the power IGBT modules, delivering the switching signals that control the power stage of the AC2000 drive.

Key Features

• IGBT gate-driver board for GE AC2000 / AC2000I drive systems (Mark V DS200 series)
• Interfaces the drive control electronics to the IGBT power stage (gate drive / isolation stage)
• Standard DS200 form factor with multiple on-board connectors for rack and power-stage wiring
• On-board status indication via LEDs
• Normal PCB coating
• Field-replaceable board for AC2000 drive cabinets

Installation Notes

1. De-energize the AC2000 drive cabinet and discharge the DC bus capacitors before handling the board (IGBT power stage holds dangerous voltages).
2. Verify the board revision (A / C) against the drive’s parts list before installation.
3. Install the IIBD board in its designated slot; seat the backplane / power connectors fully and secure the board.
4. Check the on-board LED status after power-up; confirm gate drive signals to the IGBT modules are healthy per the drive service manual.
5. Keep the original drive configuration; the board is a direct field-replaceable unit for AC2000 cabinets.

Common Questions

What does the IIBD board do? It is the IGBT gate-driver stage of the AC2000/AC2000I drive: it buffers and isolates the control signals from the drive logic and drives the gates of the power IGBT modules.

Is the DS200IIBDG1A a Mark V board? Yes — it belongs to the Mark V DS200 board family (GE Speedtronic), applied in the AC2000/AC2000I drive system. AX Control lists it as “AC2000I IGBT Driver Board” under Mark V DS200.

What revisions exist? The DS200IIBDG1A is the Functional Revision A; a “CA” variant (DS200IIBDG1ACA) is also documented. Match the revision to the drive’s parts list.

Does the board have status LEDs? Yes — the board carries on-board LEDs (9 per service data) used to indicate operational / gate-drive status.
