Development of single converter and single inverter topology and control algorithm for photovoltaic-fuel cell hybrid system

Abstract

This paper presents a novel single converter and single inverter (1Con-1Inv) topology and control algorithm for photovoltaic-fuel cell hybrid system. The new topological structure and the unique control algorithm can minimize volume and production cost of the hybrid system. In addition, system efficiency is improved by reduction of losses of hardware components, and other control factors are well regulated using just 1Con-1Inv topology with the help of the proposed control algorithm. The validity of proposed algorithm is verified with computer simulation and experiment with laboratory prototype.
