The GE IS200DAMBG1ABB is a Gate Drive Amplifier/Interface Board (functional acronym DAMB) manufactured by General Electric (GE).1
It is a critical component used in the power electronics section of GE Innovation Series Drives, which are integrated with the broader Mark VI Speedtronic Turbine Control System.2
⚙️ Primary Function: High-Power Switch Control
The DAMB board’s core function is to serve as the interface and amplifier between the low-voltage control logic and the high-voltage power switching devices, such as Insulated Gate Bipolar Transistors (IGBTs) or Integrated Gate Commutated Thyristors (IGCTs).3
- Gate Driver: It receives the precise, low-level logic signals from the central drive control board (like the Bridge Personality Interface Assembly, BPIA) and converts them into the high-current, controlled voltage pulses needed to rapidly and reliably switch the gates of the high-power IGBT/IGCT modules.
- Precision Control: Accurate gate drive signals are essential for preventing damaging conditions like “shoot-through” (simultaneous conduction) and for ensuring the efficient control of motor/generator speed and torque.4
- Interface: It connects directly to the emitter, gate, and collector terminals of the high-power modules and to the control rack interface (BPIA board).5
- Application: Boards in the DAM_ family (DAMA, DAMB, etc.) are commonly associated with specific drive power ratings. 6The DAMB is typically used in medium to high-power applications, likely the 620 Frame drive rating, and is often used in a three-board configuration (one board per phase leg) for a complete three-phase drive system.7
