ABSTRACT:

In this papersynchronous buck converter based PV energy systems for portable applications especially low power device applications such as charging mobile phone batteries are considered here the converter topology is used. The uses of soft switching technique to reduce the switching losses which is found prominently in the conventional buck converter thus efficiency of the system is improved and the heating of Mosfets due to switching losses reduce and the mosfets have a longer life. The dc power extracter from the PV array is synthesized and modulated by the converter to suit the load requirement further the comparative study between the proposed synchronous buck converter and conventional buck converter is analyzed in terms of efficiency improvement and switching loss reduction.
