Analysis of pulse-link DC-AC converter for fuel cells applications operated in zero-current-slope mode

Abstract

In fuel cells applications, current-ripple reduction is essential for conversion efficiency and life span. This paper analyzes the pulse-link DC-AC converter for fuel cells applications operated in zero-current-slope mode. As the result, in zero-current-slope operation mode, input-current-ripple is reduced. Furthermore, in this operation mode, the parameters of series LC circuit which is worked as ripple canceling are less values.
