Single Stage Power Electronic Interface for a Fuel Cell Based Power Supply System

Abstract

Fuel cell systems have generated significant interests in residential applications as well as distributed power generation due to their cleanliness, portability and suitability for electricity and heat generation. Development of a suitable power electronic interface to make the technology viable is still a challenge. This paper presents a single stage power electronic interface for fuel cell power plant suitable for stand alone application as well as for grid interface. A single stage PWM inverter is selected as a power electronic interface between fuel cell and the grid, followed by a LC filter and a step-up transformer. The simulation model is developed in MATLAB environment with control scheme implementation in qd-reference frame.
