Abstract

The paper aims to develop a solar powered multi-output efficient converter to charge three different load capacities of an electric vehicle charging station. While implementing the DC sources for multi-output charger it becomes a continuous power supply, cost effective and moreover, installing a renewable energy source such as photovoltaic system (PV) supplies green power. Hysteresis controller is connected in order to control current and to enhance power quality. A battery charger is used where boost converter is connected to it which is more efficient in using PV system. The hysteresis controller which extracts current, raises the voltage and then the battery is placed between PV array and power converter. According to Perturb and Observe method, overshoot appears in starting and slowly decreases till it reaches a stable steady state. The solar based charger is effective for converting the low voltage profile from PV panel to high voltage profile. This high voltage can be controlled and current can be limited by hysteresis controller for an efficient photovoltaic used charger. Battery is connected in between the PV and the converter for day-time charging and night time usage. The proposed converter can give out multiple-output of three different voltages like 8V, 12V, 18V. The PV powered boost converter charger with hysteresis controller is modelled in MATLAB/SIMULINK and the simulation results are verified with a scale down model.
