Résumé:
One of the major concerns in the power sector is the day-to-day increasing power
demand but the unavailability of enough resources to meet the power demand using the
conventional energy sources. Demand has increased for renewable sources of energy to
be utilized along with conventional systems to meet the energy demand. Renewable
sources like wind energy and solar energy are the prime energy sources which are being
utilized in this regard. The continuous use of fossil fuels has caused the fossil fuel
deposit to be reduced and has drastically affected the environment depleting the
biosphere and cumulatively adding to global warming.
Solar energy is abundantly available that has made it possible to harvest it and utilize it
properly. Solar energy can be a standalone generating unit or can be a grid connected
generating unit depending on the availability of a grid nearby. Thus it can be used to
power rural areas where the availability of grids is very low. Another advantage of using
solar energy is the portable operation whenever wherever necessary. In order to tackle
the present energy crisis one has to develop an efficient manner in which power has to
be extracted from the incoming solar radiation. The power conversion mechanisms have
been greatly reduced in size in the past few years. The development in power electronics
and material science has helped engineers to come up very small but powerful systems
to withstand the high power demand. But the disadvantage of these systems is the
increased power density
