Abstract :
This paper presents that a detailed steady-state and small-signal analysis of a modified Sheppard-Taylor converter using an average mode is designed for PEM fuel cell applications. Thus, a small-signal average model has all been obtained. According to the analysis above, transfer functions between duty cycle and output voltage and between input and output voltages have been also obtained, so some simplifications and design rules have been proposed to facilitate the design of the feedback loop. Simulink results are given to show the overall system performance.
