Abstract

Wireless Power Transfer (WPT) is a transmission of electrical energy across a medium without using electrical conductor or wire. There are three techniques of wireless power transfer in near-field which are inductive power transfer technique(IPT), capacitive power transfer technique (CPT) and acoustic power transfer technique (APT). Between these three techniques of wireless power transfer, IPT has the advantages of farther transmission distance and high efficiency compare with CPT and APT. Therefore, this project aims to use IPT for transferring power wirelessly. IPT will enable the power transmission from one transmitter coil to several receiver coils. Therefore, the electronic appliances such as digital clock and desk lamp are able to be power up without using cable or battery. To be specific, a class E inverter is designed in this work for converting a direct current (DC) source to alternating current (AC) source at high frequency with high efficiency. The performances analysis of the developed prototype done and discussed in term of output efficiency as well as the future recommendation of the proposed method is also presented. At the end of this project, the prototype is able to yield a 75% of efficiency.
