SOLAR PV-POWERED INTEGRATED MULTIPLE OUTPUT SYNCHRONOUS BUCK CONVERTER FOR ELECTRIC VEHICE POWER SUPPLY

This paper proposes a solar PV powered Integrated multiple output synchronous buck converter for battery operated portable applications like Electric vehicles,Mp3 players,cellular phones,Digital cameras etc.,This project deals with the operational principle, performance characteristics of a simplified dual output buck converter and solar pv powered batteries for electric vehicle power supply.The proposed converter reduces the number of switching components when compared to the conventional buck converter by achieving multiple independently regulated outputs. It also achevies high efficiency,avoids cross regulation problem, reduces both conduction and switching losses and also reduces the cost. In addition to this its dynamic behaviour is similar to the conventional buck converter and thus the simple PWM based PI contoller is used. Finally the proposed converter with solar powered battery by using mppt technique is simulated in matlab and the results are obtained
