Abstract
This paper work is carried out to reduce ripple current which is flow to the fuel cell/Battery through power electronics devices during dc-ac operation. FCs have advantages such as high efficiency, zero or low emission (of pollutant gases), and flexible modular structure With clean operating environment and high energy conversion efficiency, fuel cell is getting more and more attention, especially for the stationary power application. Such an application, either delivering electricity with utility intertie or directly supplying to residential area as a standalone power source, can be used for future distributed generation systems This paper initially describes problems associated with the fuel cell due to the ripple current such a ripple current may shorten fuel cell life span and worsen the fuel efficiency due to the hysteresis effect. The most obvious impact is it tends to reduce the fuel cell output capacity because the fuel cell controller trips under instantaneous over-current condition. This paper consists of Active filter methods through which the ripple current analyses and control.
