Abstract

This project aims to develop a charging method for electric vehicle via loosely coupled inductive power transfer (LCIPT). This method enables wireless power transmission from stationary power source to a moving load, which is the electric vehicle. Most of the existing products in this framework applied coupled magnetic resonance power transfer (CMRPT) method, i.e. the Qi technology. However, this method is limited to stationary charging. This project focuses on developing a wireless charging method to a movable load which is electric vehicle in our case. In this project, a prototype that capable to delivers power efficiently from a stationary power source to a moving load is developed. The prototype is designed in a small scale low power model of 12 Volt 5 Watt DC input to prove the proposed method applicable and could be widely used in future works through the evolution of wireless power transfer (WPT) technology. To be specific, in this project, Class E resonant inverter is used to convert the DC source to AC source at 1 MHz resonant frequency. Analysis is done on different configurations and setups of the transmission coils. Compensator circuit is also designed at the transmission coil to boost the power transfer efficiency. The output of the wireless power transmission is tested on DC-motorcar and LED. At the end, a prototype of this project is successfully developed.
