Design And Implementation Of DC DC Converter For Electric Vehicle Charging Using Effective Optimization Techniques

Abstract

Solar is considered to be an important source of renewable energy which is preferred in various applications. Electricity is generated from the solar energy by making use of the solar panels. The Current Voltage (I-V) and Power Voltage (P-V) output characteristics of solar Photo Voltaic (PV) system mainly depend on the irradiation, solar cell temperature and output voltage. Because of the nonlinear characteristics of the solar PV source, it is required to find higher peak power at any instant, maximize system efficiency and minimize the ROI (Return of Investment) on the solar PV installation. An interface is also needed to transfer power form solar PV to the load efficiently. It is also used to drive the operating point of the solar PV system to its maximum power. newlineThis work proposes the design of a solar power fed Phase Shift Full Bridge (PSFB) DC DC converter and solar power fed Resonant LLC DC DC converter with different optimization techniques. To reduce global warming, to promote green environment and due to rising fuel costs, electric vehicles are powered by batteries. These batteries can be charged by solar powered fed PSFB. The PSFB Converter and Resonant LLC converter are extensively used in Electric Vehicles (EVs) to charge EV batteries. As solar energy is a promising renewable energy source due to its abundance and easy installation, it is used as an input source for the converter. To extract the maximum power from PV panels, three Maximum Power Point Tracking (MPPT) techniques are employed. It ensures that the PV panel operates at the optimum voltage and current so that maximum power is extracted in all atmospheric conditions. The MPPT control algorithm creates switching signals which are fed to the converter, i.e., duty cycle. The control algorithms used are Metaheuristic algorithms such as the Salp Swarm Algorithm (SSA), Emperor Penguin Optimization (EPO), and Flying Squirrel Search Optimization (FSSO). Once the converter achieves the desired power, the rest of the solar power is used to charge t
