The IS200DSFCG1ADB is a GE Mark VI circuit board. This board is part of the Speedtronic line from General Electric, which is used for steam and gas turbine control. The Mark VI is one of the final Speedtronic systems, culminating over three decades of development and research. It includes power island and balance-of-plant controls.
The IS200DSFCG1ADB functions as a Gate Driver and Shunt Feedback Board. It is designed for use with Innovation Series PWM (pulse width modulated) bridges and ac drives that are either 1000 amps or 1800 amps. Please note that a 1000 amp bridge or drive requires three DSFC boards. An 1800 amp drive or bridge requires six of these boards.
The IS200DSFCG1ADB is designed to detect two types of faults:
- Undervoltage Faults: this happens when voltage between the positive and negative power supplies drops below 20V.
- Desaturation Faults: this typically happens when a driver sends an “ON” command to the IGBT and voltage between emitter and collector exceeds 10V for 4 microseconds. When this occurs, the connected BPIB board brings the gate voltage down to zero.
The board can also generate two faults, including a DI/DT fault that occurs when there is a 100% or greater step-change in the rated shunt current, as well as an IOC fault, which occurs when actual current exceeds rated current by 250%.
