High Voltage Pulse Amplifier GE IS200EHPAG1DCB for Industrial Power Systems

Description

TheIS200EHPAG1DCBis ahigh-voltage gate pulse amplifier boarddesigned for GE’sEX2100 excitation control systems. Its primary function is to receive gate commands from theESEL logic boardand amplify them into high-voltage pulses that trigger up tosix silicon-controlled rectifiers (SCRs). These SCRs regulate the generator field current, ensuring stable voltage output and safe operation under varying load conditions. Moreover, theEHPAG1DCBincludesenhanced thermal handling and fault detectioncompared to earlier EHPA models. It monitorsairflow and temperature, helping prevent overheating and misfiring. In addition to its core amplification role, the board contributes tosystem diagnostics and protection, making it essential for high-power industrial environments. Therefore, this module is widely used insteam, gas, and hydroelectric power plantswhere precise SCR control and excitation reliability are critical.
