Abstract

This paper presents performance analysis of different compact non-isolated DC-DC power electronic converters in a fuel cell-dynamic load-integrated local energy system. The first phase of work includes regulating input flow rate for fuel cells to achieve improved efficiency. The second phase includes integrated system design, operation, and control to reduce total harmonic distortion (THD) of power converters and improve power conversion efficiency. MATLAB/Simulink model, a 1.26 kW, 24V proton exchange membrane fuel cell (PEMFC) integrated with DC-DC buck converter, boost converter, buck-boost converter, sepic converter, cuk converter, single phase inverter and dynamic load profile are considered. DC-DC boost converter is found as the most suitable compared to other power converters in terms of speed of response, power quality (%THD), and efficiency. Finally, performance of the DC-DC boost converter is validated by experimental results of a practical PEMFC stack integrated dynamic load management system. Boost converter achieves efficiencies of 98.57 % and 97.6 % for R and RL loads, respectively, and maintains good power quality with %THD levels of 0.58 % and 1.36 % at the inverter side. The connected single-phase off-grid inverter achieves efficiency of 97.36 % under RL load. The outcome provides an efficient energy conversion solution for waste-to-electricity and off-grid local community demand-side management.
