The primary function of the IS200IGDMH1BCC is to drive and protect the Insulated Gate Bipolar Transistors (IGBTs) in the power conversion stages.

  • Gate Driving: It receives low-power logic signals from the main control board and amplifies them into the necessary high-current, high-voltage gate signals to rapidly and precisely switch the large power IGBTs ON and OFF.

  • Power Control: By controlling the IGBT switching, the system can regulate high amounts of power to control parameters like voltage, frequency, and current. This is essential for:

    • Generator Excitation: Controlling the current to the generator’s field winding to regulate output voltage and reactive power (in EX2100).

    • Industrial Drives: Controlling the speed and torque of large motors.

  • Protection: The board features built-in safety circuitry, notably desaturation fault detection, to protect the expensive IGBT power modules from catastrophic failure due to short circuits or overcurrent events.

  • Isolation: It employs transformers to ensure galvanic isolation between the sensitive, low-voltage control electronics and the high-voltage power circuits.

🔎 Technical and Revision Details

  • System Series: Mark VI Speedtronic and EX2100.

  • Functional Acronym: IGDM (IGBT Gate Driver Module).

  • Form Factor: It is a small, specialized PCB that typically does not have a traditional faceplate but is attached to a moldable sub-strata for support and stability.

  • Connectors: The board is populated with several connectors for signals and power, including vertical male two-pin connectors (often labeled J1 and J2) and a single-pin connector (J3), along with plastic connectors and terminal connections.

  • Auxiliary Board: An auxiliary board is often soldered onto the primary PCB to house additional components, such as capacitors, and ensure effective heat dissipation.

  • Revision: The suffix H1BCC indicates a specific assembly revision of the base IS200IGDMH1B design. The core functionality is shared across the various H1B manufacturing variations.

  • Onboard Memory: It includes an EEPROM for storing essential block definitions and configuration parameters necessary for drive performance optimization.
