IS200FGPAG1A

About the IS200FGPAG1A

• The IS200FGPAG1A is a Gate Driver Module / Gate Pulse Amplifier Board developed by General Electric (GE).
• It is part of the EX2100 product line / EX2100 Excitation system / LS2100 Static Starter Control System.
• Crucial for amplifying gate pulses to drive power semiconductor devices (e.g., IGBTs, thyristors) in exciter systems and high-voltage inverter systems.

Functionality & Features

• Provides reliable and efficient drive signals to power semiconductor devices.
• Ensures precise control and protection of these devices, enhancing system performance and reliability.
• Acts as the gate driver, switching power supply, and SCR status monitors for the LCI (Line Commutated Inverter).
• Receives gating commands from the LCI control via fiber-optic cables.
• Each FGPA provides sufficient gate power and duration for one phase of an SCR bridge.
• Built-in diagnostics: Continuous self-diagnostics for fault detection and logging, including undervoltage detection in the gate power supply.
• Protection Features: Includes over-voltage, over-current, and short-circuit protection.
• High-Voltage Operation: Supports gate drive voltages up to 1,200 Vdc (peak).
• Versatile Output Voltage: Operates with output voltage levels of 0-2300 VAC, 4160 VAC, or 6600 VAC.
• AC to DC Conversion: Switching power supply circuit converts AC input (e.g., 120 V AC) to required DC control voltages (e.g., P5 for logic, P40 for back porch gate, P90 for gating).
• Interfaces with CTs on FHVA boards which then interface with SCRs.
• Temperature Monitoring: Can accept feedback from thermal switches on SCR heatsink assemblies for overtemperature alarms and trips.
