The GE IS200DAMAG1BCB is a Gate Drive Amplifier/Interface Printed Circuit Board (PCB), with the functional acronym DAMA, manufactured by General Electric (GE).1
It is a critical component used within the Innovation Series Low Voltage Drives that are part of the broader Mark VI Speedtronic Turbine Control System.2
⚙️ Primary Function: IGBT Gate Driver
The board’s main function is to bridge the gap between the sensitive, low-power control electronics and the rugged, high-voltage power switches in the drive system.3
- Gate Amplification: The DAMA board takes the precise, low-level logic control signals from the drive’s central control board (the Bridge Personality Interface Assembly, BPIA) and amplifies them into the high-current, precise voltage pulses required to quickly and reliably switch the gates of the external Insulated Gate Bipolar Transistor (IGBT) modules.4
- Interface: It connects directly to the IGBT modules (typically high-power modules like the Powerrex CM1000HA-28H) via dedicated connectors.5
- System Integration: This board is specifically designed for the 620 Frame drive power rating—the largest frame in the Innovation Series.6 A complete three-phase drive system typically uses three of these boards (one for each phase leg).7
- Protection: Though its official name is a Gate Drive Amplifier, it is often marketed as a “Snubber Control Board” or “Inverter Snubber Board” because its accurate and swift gate driving function is essential for mitigating damaging voltage transients and preventing simultaneous conduction (shoot-through) in the IGBTs.
