The solar electric vehicle solves many problems related to the environment and is the best pollution free method. We need to make use of them so that we can reduce our dependence on fossil fuels. Electric vehicle batteries are quite different from those used in consumer electronic devices such as laptops and cell phones. They are required to handle high power and high energy capacity within a limited space and weight and at an affordable price. Solar electric vehicles are full electric vehicles, only using electricity and no petrol or diesel for energy. As such, they produce zero direct carbon emissions. The solar energy may be varying time to time so MPPT algorithms are necessary because PV arrays have a nonlinear voltage-current characteristic with a unique point where the power produced is maximum. This point depends on the temperature of the panels and on the irradiance conditions. Both conditions change during the day and are also different depending on the season of the year. The irradiation can change rapidly due to changing atmospheric conditions such as clouds. The negative output buck-boost converter provides inverse output voltage. The converter has wide conversion ratio with no current spike in output. As compare to other negative output converter the gain of new negative output buck-boost converter is high. All the simulation works are done in MATLAB/SIMULINK software. TMS320 is used for generating control pulses for the switches. The prototype of proposed system is setup and verified its performance.
