Wireless power transfer system with reduced voltage stress on compensation capacitors

The paper deals with proposal for circuit configuration of series-series (SS) compensated wireless energy transfer (WET) system with reduced voltage stresses on compensation capacitors. Nowadays, a huge effort is given for development of reliable, efficient and robust wireless charging systems and therefore the circuit configuration and component selection is crucial to meet suitable operational characteristics. For this purpose, the current trends in WET systems are outlined in the first section. Next, the analysis of frequently utilized WET system configuration is provided and most critical issues related to practical utilization are discussed. Consequently, the proposal of how to eliminate negative aspects is given. All theoretical statements are supported by simulation analysis and consequent verification.
