Investigating the performance of Fuel Cell based Distributed Generation systems under unbalanced loading

this paper presents the study and simulation of two Fuel Cell based Distributed Generation (FCDG) systems. Each of these systems consists of a validated PEM fuel cell model, a DC-DC Boost converter circuit and a 3-phase SPWM inverter circuit. The main difference between the two FCDG systems exists in the DC-DC converter circuit; the first circuit is a DC-DC Boost converter with a 1-phase 3-winding high frequency transformer and the second circuit is the conventional DC-DC Boost converter. The two FCDG systems have been studied under balanced and unbalanced load connection and disconnection. The simulation analysis has been done using MATLAB/SIMULINK platform.
