摘要

In recent years the development of alternative energy source is getting more importance because of high quality characteristics in power generation system with low cost. The proliferation of DC-DC converter is widely used for high power and low voltage applications. In such cases, the ultra-lift Luo converter is the suitable one compared to voltage lift VL Luo-converter and super-lift (SL) Luo-converters because of their limitations in voltage transfer gain and more voltage ripples. This paper proposes the proportional integral (PI) and fuzzy logic (FL) controllers for the fast and efficient operation of ultra-lift (UL) Luo-converter. An air breathing fuel cell (ABFC) stack is developed and which is taken as an input power source to the ultra-lift Luo-converter. This paper will give focus on design, mathematical analysis and operation of fuel cell powered DC-DC converter is incorporated with PI and FL controllers which are simulated using MATLAB/Simulink software. Furthermore, simulation results of ABFC are also presented to review the effects of temperature from 30°C-70°C in fuel cell voltage. The dynamic response of PI and FL controllers are sifted for line as well as load voltage regulations and the simulation results are presented using MATLAB/Simulink.
