Abstract

In the recent years, Wireless Power Transfer (WPT) system is one of a groundbreaking technology that makes everyday life easier. This system allows power transfers from one plate of metal conductor to another without any physical touch. The WPT system is divided into their own category of fields and these category classified into acoustic power transfer (APT), microwave power transfer (MPT), inductive power transfer (IPT), and capacitive power transfer (CPT) and in this particular project the CPT system is chosen for its advantages compared to other system. Moreover, this technology will solve the problem with conventional electrical transmission. The objective of this project is to develop a capacitive type (CPT) mobile phone charger. The CPT system used a SMPS as a supply to the transmitter plate to convert AC supply into DC supply to transfer the electric field to the receiver plate. While, the receiver part will charge the mobile phone. The observation will be made by using a different size of transmitter and receiver plates, the type of material used and the position of the plates to compared the efficiency of the project. As the conclusion, this project is very user-friendly and the goal is to improve the conventional charging system into a wireless system.
