TLDR
In this paper, a three-level step-up converter is implemented to boost the fuel cell stack voltage of 90V to 340V and two feedback control loops are designed to make the system operate in stable conditions.Abstract:
This paper presents a system model of fuel cell based distributed generation systems (DGS) in a standalone AC power supply system. Non-isolated high step-up DC-DC converters are required widely in the industrial applications. Many of these conventional DC-DC converters have the disadvantages of operating at high duty-cycle, high switch voltage stress and high diode peak current. A three-level step-up converter is implemented to boost the fuel cell stack voltage of 90V to 340V. This high DC link voltage is fed to the voltage source inverter and interfaced with the load. Two feedback control loops are designed to make the system operate in stable conditions. This system configuration is suitable for low-power applications. The Performance of the developed system is analyzed in MATLAB/Simulink environment under steady state and transient conditions.read more
