Abstract
This article aims to develop a solar powered efficient DC-DC converter to charge electric vehicle. While implementing the DC sources for boost converter with coat circuit charger it becomes continuous power supply. In the boost converter with coat circuit, which raise the input voltage 3 time higher from the voltage of battery or PV cell. According to this method of boost, the voltage is boosted to three times higher than normal voltage rate which is stored in the battery for steady supply of voltage. The solar based dc-dc boost converter charger is effective for converting the low-level voltage to high-level voltage of a converter. Over voltage and current can be controlled and limited by coat circuit to be an efficient PV charger. The battery is connected between PV and converter to store energy from sunlight. By this of boost converter, the losses which occur is reduced and produce improved voltage conversion ratio. Improvising voltage conversion ratio using boost converter with coat circuit is premeditated using MATLAB and the simulation outputs have been verified with a model.
