GE IS200BICMH1A IGBT gate driver card

د.إ8,888.00

GE IS200BICMH1A is a specialized Printed Circuit Board (PCB) known as the IGBT Gate Driver Card (1$\text{BICM}$).2 It is a critical component in General Electric’s Drive Control Series, which is integrated with the Mark VI Speedtronic Turbine Control System for controlling large, high-power equipment.3

Its primary function is to serve as the high-speed, protective interface between the drive’s low-voltage digital control processor and the high-voltage IGBTs (Insulated Gate Bipolar Transistors) in the power conversion bridge.4

⚙️ Key Functions and Technical Details

The $\text{BICM}$ card ensures that the IGBTs, which switch high power on and off thousands of times per second, operate safely and efficiently.

  • IGBT Gate Drive: It generates the precise, high-current pulses needed to rapidly turn the IGBT gates on and off, minimizing switching losses (heat) and ensuring accurate power control.5

The GE IS200BICMH1A is a specialized Printed Circuit Board (PCB) known as the IGBT Gate Driver Card (1$\text{BICM}$).2 It is a critical component in General Electric’s Drive Control Series, which is integrated with the Mark VI Speedtronic Turbine Control System for controlling large, high-power equipment.3

Its primary function is to serve as the high-speed, protective interface between the drive’s low-voltage digital control processor and the high-voltage IGBTs (Insulated Gate Bipolar Transistors) in the power conversion bridge.4

⚙️ Key Functions and Technical Details

The $\text{BICM}$ card ensures that the IGBTs, which switch high power on and off thousands of times per second, operate safely and efficiently.

  • IGBT Gate Drive: It generates the precise, high-current pulses needed to rapidly turn the IGBT gates on and off, minimizing switching losses (heat) and ensuring accurate power control.5
  • Built-in Protection: The board has on-board circuitry for essential protective functions, including:
    • Overvoltage Protection
    • Overcurrent Protection6
    • Short Circuit Protection
  • Watchdog Monitoring: The $\text{BICM}$ actively monitors a watchdog signal from the main $\text{DSPX}$ processor. If the signal fails (indicating a processor hang-up), the $\text{BICM}$ disables the bridge firing within microseconds to prevent catastrophic failure.
  • Diagnostics: The faceplate features an 7$\text{IMOK}$ LED indicator for general board health and multiple User Test Points (8$\text{TP}$) for diagnostics, corresponding to signals like 9$\text{VAB}$, 10$\text{VBC}$ (phase-to-phase voltages), and 11$\text{VDCP}$ (DC bus voltage).12
  • Component Density: The board is highly complex, populated with over 150 capacitors, 300 resistors, and 100 integrated circuits for signal conditioning and control.13

⚠️ Installation and Replacement Notes

  • Slot Restriction is Mandatory: The board is explicitly labeled and designed to be installed “INSTALL IN SLOT 5 ONLY” of the VME rack assembly.14 Installing it in any other slot will likely cause damage to the board and the backplane.15
  • Revision Match: The H1A suffix specifies the exact hardware and firmware. Due to the board’s critical role in high-speed control timing and safety logic, you must use an exact matching revision when replacing the board.
  • Safety: This board interfaces with the high-voltage power side of the drive. Strict Lockout/Tagout ($\text{LOTO}$) and safety verification are mandatory before handling.
