The GE IS200IGDMH1BCC is a specific revision of the IGBT Gate Driver Module used within the GE Mark VI Speedtronic Turbine Control System and the associated EX2100 Excitation System.1
This board is a critical interface for high-power control.
⚡ Function and Application
The primary function of the IS200IGDMH1BCC is to control the high-power Insulated-Gate Bipolar Transistors (IGBTs).
-
Gate Driving: It receives low-power, precise switching signals from the main control logic (like the Mark VI processor) and converts them into the necessary high-current, high-voltage pulses required to switch the massive IGBT power modules rapidly and efficiently.
-
System Context: It is essential for power conversion applications, such as the Static Starter (used for turbine startup) and the Generator Excitation System (used to regulate the generator’s output voltage and reactive power).
-
Isolation and Protection: It provides crucial electrical isolation between the low-voltage control electronics and the high-voltage power circuits, while also incorporating protection features (like desaturation detection) to safeguard the expensive IGBTs from faults.
🔍 Understanding the Part Number
The detailed part number conveys important information about the board’s configuration and environmental protection:
| Part Segment | Meaning |
| IS200 | Identifies the board as a component of the GE Mark VI series. |
| IGDM | IGBT Gate Driver Module (Functional Acronym). |
| H1B | Specifies the core hardware design and functional revision. |
| CC | Often indicates the type of protective coating. The double ‘C’ generally signifies a Heavy Conformal Coating, a special polymeric film applied to the PCB to protect it from moisture, dust, and corrosive contaminants common in industrial environments. |
Replacement Note
It is a standard maintenance practice that if the high-power IGBT module connected to this driver board fails, the IS200IGDMH1BCC is also replaced. This is because a power module failure frequently causes secondary damage to the delicate gate driver circuit.
