Features:
- IS200IGDMH1B provides the gate-driver endpoint for an IGBT bridge cell.
- A fiber-optic link connects the IGDM board to the IS200FOSA interface.
- Continuous optical return lets bridge control monitor communication with the cell.
IS200IGDMH1B participates in a drive bridge where each indicated cell has a defined optical communication position.
Link verification for IS200IGDMH1B depends on the observed order of the gate-driver LEDs rather than a software-generated pass/fail explanation.
Because several hardware and wiring conditions can interrupt return light, IS200IGDMH1B troubleshooting must keep the optical path, board power, and associated IGBT state separate.
The General Electric IS200IGDMH1B IGBT Gate Driver Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Optical Cell Path
- Cell endpoint: IGDM provides the gate-driver board at the IGBT bridge cell.
- Interface board: IS200FOSA is the fiber-optic hub for the gate-drive links.
- Return signal: Normal operation includes continuous light from IGDM to FOSA.
- Trip basis: Loss of the return signal creates the IGDM communication fault.
Link Verification Method
- Wizard: The Fiber-Optic Test checks FOSA-to-IGDM connections.
- Observation: Each gate-driver LED must appear in the defined cell sequence.
- Repetition: The sequence is repeated three times unless aborted by a user or fault.
- Result limit: The test supplies no automated diagnostic conclusion.
Lost-Link Investigation
- Board candidates: IGDM, FOSA, CPFP, and BICM remain within the fault boundary.
- Fiber path: A damaged or misplaced optical connection can remove return light.
- Power path: CPFP distribution wiring and supply condition must also be checked.
- IGBT condition: A desaturation event can produce the same communication symptom.
Bridge Test Coverage
- Short paths: The cell test detects unintended conduction in the inverter bridge and load.
- Open paths: Expected bridge conduction paths and shunt feedbacks are evaluated.
- Voltage feedback: The wizard checks whether bridge voltages are measured correctly.
- Dynamic brake: Additional cell checks run only when that option is installed.
