IS200EPSMG2AED is an Exciter Power Distribution Module developed by GE. It is a part of EX2100 control system. EPSM is an integral component within both the EX2100 Excitation Control System and the EX2100 Regulator Control. In the Regulator Control, specifically, the EPSM Group 2 modules (EPSMG2) are utilized, which incorporate an additional EPSD Exciter Regulator Power Supply Daughter board.
EPSM comprises two primary sections, namely a buck-regulator and a push-pull inverter. The intricate design of these sections plays a vital role in converting and regulating input voltages to meet the diverse power requirements of the control system.
The buck-regulator functions as the initial stage in the power conversion process within the EPSM. Its primary objective is to efficiently lower or "buck" the input voltage to a specific intermediate voltage level, typically around 50 volts DC. This intermediate voltage serves as a pivotal stage in the subsequent power supply steps within the system. The buck-regulator achieves voltage regulation by controlling the duty cycle of a switching element, such as a transistor or a MOSFET. By adjusting the duty cycle, the buck-regulator ensures that the output voltage remains stable and within the desired range despite fluctuations in the input voltage.
Following the buck-regulator, the EPSM incorporates a push-pull inverter to generate multiple output voltages necessary for the proper operation of the control system. This stage involves the conversion of the intermediate 50 volts DC voltage into various output voltages required by different components within the system. The push-pull inverter accomplishes this by utilizing a pair of transistors or other switching devices arranged in a push-pull configuration. This configuration allows for the efficient generation of alternating current (AC) waveforms from the direct current (DC) input. By carefully controlling the switching of these devices, the push-pull inverter ensures the generation of stable and accurate output voltages tailored to the specific requirements of the control system.
Central to the push-pull inverter is a transformer that plays a pivotal role in the power conversion process. This transformer not only facilitates the conversion from the intermediate voltage to multiple output voltages but also provides high-voltage isolation between the input voltage source and the output supplied to the control system.
In the context of the Regulator Control, EPSMG2 modules are employed, which incorporate an additional IS200EPSDG_A Exciter Regulator Power Supply Daughter board (EPSD). This daughter board further enhances the capabilities of the EPSM, contributing to the precision and reliability required in the regulation of the control system.
