GE IS200EGPAG1A IS200EGPAG1ADD stores energy using one electrolytic capacitor. This capacitor provides 22 µF at 35V rating for gate pulse filtering. Consequently, the board maintains clean firing signals during 10 microsecond transients. Therefore, SCRs receive reliable gate pulses in high-noise exciter environments.
Design and Integration
Both the GE IS200EGPAG1A and IS200EGPAG1ADD versions share identical gate amplifier topology. These boards use four-layer PCB construction with high-voltage isolation between input and output. Consequently, the GE IS200EGPAG1A IS200EGPAG1ADD operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 120 mA typical current from the 24V DC supply. Each gate channel provides isolated drive for individual SCRs. We recommend mounting the board close to the SCR modules for best performance.
Practical Application
This gate pulse amplifier board boosts low-voltage logic signals to drive SCR gates. It receives firing pulses from the exciter regulator board. The GE IS200EGPAG1A IS200EGPAG1ADD then amplifies and isolates each pulse for thyristor firing. Therefore, it ensures reliable SCR triggering in GE exciter control systems.
