Abstract

This wireless power transfer (WPT) is to develop one of the tools for power transfer through wireless. In this project wireless power transfer with multilevel output voltage was built. The output from this project is 12V and 5V. Normally, most of the appliances in home need the cables to transfer the electrical energy with different voltages from power source. The more appliances used, the more cables needed. The cables have high risk to damage or loosened and can expose into electrical short or maybe fire because they are not tidy and messy. So, the numbers of cables used should be minimized to avoid the dangerous risk. To overcome this problem, wireless power transfer should be developed by using concept of electromagnetic methodology circle type. There are certain ranges that power can be transfer efficiently. As a result from this project, there are different types of graph by using different resistor which is 1 kΩ and 330 Ω at a certain distance. The gains are different from 1 kΩ and 330 Ω by using different resistor. It recorded by the both resistor shown the low gain when the distance of receiver are far away from transmitter. The efficiency also shown the different value when the distance far away. The efficiency is less than 1 %. The distance used in this project is 0 cm to 3 cm. So, the distance of this project give affects to the output result which is 5 V and 12 V to light the LED light. The important part of this project is to achieve multilevel output voltages of WPT to be transferred.
