Design And Operation of high frequency inverter with PFC In Wireless Charging Of Electric Vehicles

Abstract

This paper presents a Wireless charging of a battery in an electric vehicle (EV) is crucial, hence the attention of the paper is on the proposal of an EV charging circuit employing a high frequency single phase inverter to achieve high voltage at receiver end by using voltage doublers. The proposed charging circuit includes a diode bridge rectifier, PFC converter, voltage double and single-phase inverter. To achieve a high output voltage on the receiver end, we use a voltage double rather than a rectifier to attain high output voltage over receiver end of the proposed system. The design and operation of the PFC converter and voltage double are explored. The purpose of a power factor correction converter (PFC) in proposed system is to increase of power factor and thus power quality. It also boosts efficiency and reduces ripple factor at dc vol. Vol. doublers is an electrical ckt. This is connected in receiver end ofthe system that creates an output value that is twice the input voltage. It is a vol. multiplier with a increase feature of 2. Hence output voltage is twice than the input voltage can be attained. To simulate and investigate a single-phase inverter, the sinusoidal PWM is selected for the planned system to achieve high frequency. Inductive power transfer (IPT) technology is used to charge electric vehicle battery. A simulation investigation of the suggested charging ckt is passed out in MATLAB / SIMULINK.
