Abstract

The project is about Capacitive Power Transfer System (CPT) which is the Wireless Power Transfer (WPT) that transfer electric field. WPT is the process of transferring power from one circuit onto another without passing through any manmade conductive elements interconnecting them. The simplicity and low cost of capacitive power transfer makes them very interesting for wireless charging stations and galvanically isolated power supplies. Major benefits include low electromagnetic radiation, simple structure of couplings, lightweight, low cost, position flexibility and high frequency applicability. Primary part for this project contains the application of Microcontroller, High Speed Current Driver and Single Phase Class E MOSFET Converter Circuit. PWM technique is used to generate switching control signal for Class E MOSFET Converter Circuit. Then, power will transfer from primary plate to secondary plate by using capacitive plate. Next, power will receive to secondary part which contains of Rectifier and Darlington Circuit for USB specification such as charging handphone. The performance of the system will be testing by measuring efficiency of power transfer and the relationship between output voltage and distance between primary plate and secondary plate.
