摘要：Fuel cell based power generation is emphasized due to its capability of supplying electricity in the areas where there are hardly any source of conventional or non-conventional power generating options to adopt. Moreover, the added advantage is that it can be used during peak loads. Fuel cell based power generation is well known due to its clean operation, transportability, suitability and flexibility for power generation. This paper gives the outlook of modeling of a fuel cell power generation system, a multilevel inverter and their control algorithms. The design system is used in isolated loads as well as grid connected system. Different carrier signals have been used with two different modulating signals for multilevel inverter for lowest Total Harmonic Distortion (THD) in the output using seven levels and eleven level inverters. The inverter output is fed to consumer loads. The MATLAB/SIMULINK software is used for modeling this system. The developed fuel cell based distributed power generation system worked satisfactorily, when it is connected to grid and used in isolated mode or hybrid mode.
