Optimizing Wireless Power Systems: Comparative Analysis of Electronic Converters and Techniques

This research aims to advance wireless power transfer (WPT) technology, focusing on increasing efficiency and transmission distance between the sending and receiving coils. The paper will explore the utilize of advanced powerelectronic converters for converting direct current to alternating current with maximum power transfer, this assessment was conducted on three distinct categories of inverters, namely classE, class-D, and H-bridge, in order to establish a comparison among them based on the identical parameters of the system. After formulating the proposed system, a simulation using matlab has been conducted for distances that vary across three variables. From the outcomes of this simulation, it has been determined that the class-E inverter exhibits the highest level of efficiency and power transfer in relation to the suggested battery charging system. Key words. Wireless power transfer (WPT), Inductive coupling wireless power transfer (ICWPT), electric vehicle (EV).
