Project Summary

This project presents a feasible and reliable highly-efficient Charger based on Wireless Power Transfer (WPT) for Electric Vehicle (EV) charging applications. Inverter based Active Power Filter in used to eliminate the harmonics. CC-CV mode is implemented for smart charging. A laboratory prototype of 100W is built and tested to test the efficiency of the design. As per experimental results, high efficiency is achieved at the distance of 20cm and maximum sliding distance of 10 cm at universal input voltage 220V AC of 50Hz frequency.

Project Objectives

There are four main objectives of this project.

• Smart Charging to Prolong Battery Life
• Active Power Filtering of Harmonics
• Increasing Distance efficiency
• Increasing Alignment efficiency

Project Implementation Method

The simulations are carried out using different software tools which include MATLAB and Simulink, Proteus, LiveWire, and PSIM.

Benefits of the Project

Highly efficient Wireless Charger is designed in which Smart Charging is implemented which prolongs the battery life as it prevents the battery from undercharging and overcharging. Similarly, Active Power Filtering of the harmonics is carried out through the Inverter as the harmonics which are produced due to non-linear load damage the components llife as well as grid, so these harmonics are filtered using Active Power Filter.

Technical Details of Final Deliverable

There are basically two modules of Project. The Transmitter side and Reciever Side. The Transmitter Site consists of a Step-down Transformer to convert 220v to 12v. Then Bridge Rectifiers converts AC to DC and bank of filtering capacitors to convert pulsating DC to pure DC. Then there is a circuit for voltage regulation and then gate driver circuitry. This gate driver circuitry drives the MOSFETs which transmit the power through the transmitting coils. At reciever site, there is a recieving coil and then a bridge of diode to smoothen the DC recieved from recieving coils. Then there is bi-directional DC-DC converter and then a control circuit of CC-CV control and then a 12V DC battery.
