Abstract

Electrical autonomous vehicle had been a trend in nowadays. However, transportable distance was one of the main concerns for the system. Although battery technologies had become more advanced, the distance covered by electrical vehicles were still be limited. In this project, a wireless power transfer technology using an inductive approach to power up the vehicle while moving had been proposed. Generally, this ‘on the go’ wireless charging or dynamic charging, had been archived by embedded the transmitter coil underneath the road and a receiver coil had placed at the vehicle i.e. car. A Class E Inverter had been designed with operating frequency 1 MHz to ensure the power loss was minimal in the IPT System. Furthermore, a LCCL Impedance Matching technique had been proposed to maintain the output power while a drastic change in alignment happens in the power transmission. At the end of the project, a prototype had been developed with a Line Follower Car which powered without battery. The efficiency of this system was 28.73 % with an output power of 3.1022 W.
