FPGA based controller for fuel cell

Abstract

This dissertation presents a fuel cell controller.A model is developed for Fuel Cell. We mainly deal the control of the fuel cell under a variety of different parameters, and implementation of the control system in an FPGA using VHDL. The output voltage of Fuel Cell is controlled or conditioned by some controllers; it may be digital or analog. Recently, the importance of the PWM has increased as it became an integral part of all the electronics system. There are two basic techniques for PWM generation, analog and digital. The disadvantages of the analog methods are that they are prone to noise, and they change with voltage and temperature change, they suffer changes due to component variation. To overcome the problem, associated with the analog technique, various types of digital technique are available. Implementation of these techniques in VHDL is done.
