GE IS200IGPAG2AED Gate Drive Power Supply Board

د.إ8,888.00

GE IS200IGPAG2AED is a specialized Gate Drive Power Supply Board (IGPA) developed by General Electric.1 It is a critical component within GE’s high-power control systems, most notably the EX2100 Excitation System and often utilized in large drive applications associated with the Mark VI Speedtronic Turbine Control System.2

⚙️ Core Function and Role

The board’s primary function is to provide the dedicated, regulated, and galvanically isolated DC power necessary to operate the high-speed switching circuitry.

  • Dedicated Power Source: The IGPA board converts the system’s incoming AC or DC power into the stable DC gate drive voltage (typically $\pm 15$ VDC or similar) required to switch the gates of power semiconductor devices like IGBTs (Insulated Gate Bipolar Transistors).

  • Isolation: A key feature is providing galvanic isolation between the sensitive, low-voltage control electronics (where the processor resides) and the high-voltage power conversion stages. This isolation prevents electrical noise and large voltage spikes from damaging the control modules.

  • System Integration: In the EX2100 Excitation System, this board ensures the gate drivers have the precise power needed to switch the power bridge components (often thyristors or IGBTs), which in turn controls the DC voltage and current supplied to the generator’s field winding, regulating the generator’s output.3
