The IS200EPSMG2A is an essential component of the GE EX2100 Series excitation turbine control system. It functions as a power supply module, converting input voltage into various output voltages required for the system’s operation. This module is specifically designed for use in the regulator control section of the EX2100 system.

Key Features and Components

• Part of EX2100 Series: Integrated into the broader GE excitation turbine control system.
• Exciter Power Supply: Converts input voltage into necessary output voltages.
• EPSMG2 Classification: Belongs to Group 2 modules used in regulator control.
• IS200EPSDG_A Daughter Board: Integrated Exciter Regulator Power Supply Daughter board for enhanced performance.
• Buck Regulator and Push-Pull Inverter: Core components for voltage conversion.
• Isolation Transformer: Ensures safety and prevents voltage fluctuations.

Functionality

The module operates in two primary stages:

1. Buck Regulator: Converts the input voltage to a stable 50V DC intermediate voltage.
2. Push-Pull Inverter: Utilizes the intermediate voltage to generate multiple output voltages through a transformer.
