The Modeling And Simulation For The Filter Circuit Of The Emergency Power Supply

EPS is the simplification of Emergency Power Supply. With the continuous progress of the era, the society has confronted more and more modernization. In recent years, EPS power supply system is widely used in fire protection systems and emergency illumination systems because of its significant performance and good environment protection, but these fields have no equipments complex and precise and are not exigent to the quality of the power supply. Now we want to apply EPS to these complex and precise equipment, therefore we need EPS to be more qualified and a new filter technology. This paper put emphasis on the output filter circuit of the EPS system, and introduces the theory, structure and characteristic of filter circuit, and the calculations methods. Finally, based on the principle analyses, we use computer software to simulate and calculate the equation of circuit loss for the future prediction of the filter circuit loss.
