Abstract:
This paper mainly deals the control of the fuel cell under variation of different parameters,and implementation of the system in VHDL.As we know that not any voltage source,wether it is traditional energy source or fuel cell system behaves as an ideal source.The output of these cells depends upon some parameter of the cell.To control the output voltage of a fuel cell,we need some controller,it may be digital or analog.
At the present time,PWM has become an integral part of all the electronic system.This technique has some salient feature,due to which it has replaced the traditional use of digitally juston off signal to control the switching action of the converter.There are two basic techniques of 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 has done.
