FUNCTIONAL DESCRIPTION:
IS200EPSMG2A is an Exciter Power Supply Module Manufactured and designed by General Electric as part of the EX2100 Series used in the GE Excitation Turbine Control System and the EX2100 Regulator Control. EPSM Group 1 modules (EPSMG1) are used in the excitation control system and EPSM Group 2 modules (EPSMG2) are used in the regulator control. EPSMG2 includes an IS200EPSDG_A Exciter Regulator Power Supply Daughter board (EPSD) mounted to it. The EPSM is comprised of 2 major sections, a buck regulator and a push-pull inverter. The buck-regulator converts the input voltage to a 50 V dc intermediate voltage. This intermediate voltage is then applied to a push-pull inverter to create the required multiple output voltages. The transformer used in the push-pull inverter provides high-voltage isolation between the input voltage source and the output supplied to the control system.
EX2100 EXCITATION CONTROL SYSTEM APPLICATION:
EPSMG1 converts 125 V dc from the power distribution module (PDM) into the voltages required for the EX2100 excitation control. Three independent EPSMG1s supply power to each of the controllers M1, M2, and C. They are mounted in the IS200EPBPG_A Exciter Power Backplane (EPBP) located below the IS200EBKPG_A Exciter Backplane (EBKP) in the control cabinet. Connectors P1 and P2 carry power from the EPSMG1 to EPBP for cables to EBKP and other boards. The EPSMG1 supplies +5 V dc, ±15 V dc, and +24 V dc to the control assembly backplane. Power is also supplied to external modules as follows:
EX2100 REGULATOR CONTROL APPLICATION:
EPSMG2 converts the dc link bus voltage into the voltages required for the EX2100 regulator control. In simplex systems, one EPSMG2 is mounted in the IS200ERBPH_A Exciter Regulator Backplane (ERBP). In redundant systems, one EPSMG2 is mounted in ERBP (M1) and a second EPSMG2 is mounted in the IS200ERRBH_A Exciter Regulator Redundant Backplane (ERRB, M2/C). The EPSD that is mounted on EPSMG2 modifies the power input path to allow EPSMG2 to accept higher voltages by increasing the creep and clearance. It also provides a fuse between the regulator power source (DC link) and the buck regulator. The EPSMG2 supplies +5 V dc, ±15 V dc, and +24 V dc to the ERBP and ERRB. Power is also supplied to external modules as follows:

What is the function of an Exciter in electronic systems?
The exciter generates the high-frequency signal required for transmission or operation of the system. It serves as a precursor to the main power amplification stage.
Why is a dedicated power supply needed for the Exciter?
The Exciter requires a stable and reliable power source to ensure proper operation and performance. A dedicated power supply helps in providing consistent power output and prevents fluctuations that could affect the exciter's functionality.
What are the key features to consider when selecting an Exciter Power Supply Module?
Voltage output stability, current rating, efficiency, reliability, protection features (such as overvoltage and overcurrent protection), and compatibility with the exciter system are important factors to consider.
