GE IS200EBRGH2A EX2100E GATE PLS 42-77MM

A thyristor bridge is a power electronic circuit that converts AC to DC power to supply the generator’s field. The IS200EBRGH2A board controls this process with incredible precision.

  • Gate Pulse Generation: The board receives control signals from the main controller (like a DSPX) and then generates a series of timed electrical pulses called “gate pulses.” These pulses are sent to the gate terminals of the SCRs in the bridge.
  • Precision Timing: The timing of these pulses is critical. By precisely controlling the firing angle of the SCRs, the board can regulate the amount of DC current flowing into the generator’s field, which in turn controls the generator’s output voltage. This is a core function of the excitation system.
  • 42-77MM: The “42-77MM” in the part number likely refers to the mechanical dimensions or a specific form factor of the board, such as its width, suggesting it may fit in a narrower slot than the 100MM version.
  • System Integration: The EBRG board works in conjunction with the main control card and other I/O boards to form the complete excitation control system.
  • Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.
