Reduction of Lower Harmonics and Improve the Efficiency of a Wireless Charging System by using Quasi-z-source Converter

Objective: In this paper we presented the concept of power transfer without using any type of conductor or wire i.e. Wireless Power Transmission (WPT) for charging a battery or other devices like cell phones and tablets. Methods/Statistical analysis: The WPT has been avoided because, it provides less efficiency. But in this paper quazi z-source converter has been used, so that we can improve the efficiency and reduce the harmonics which are caused by using wireless charging system. Findings: By using MATLAB software, the wireless charging system has been designed and tested. The results obtained by using the proposed method have an increase in efficiency when compared to the conventional method. Improvements: By using the proposed method, there is also an increase in its input factor and achieves superior performance.
