This paper compares the characteristics of serial, parallel and LCC compensation topologies of secondary-side in wireless powering systems with a constant-current primary-side. The topologies characteristics of power, efficiency and load are carefully analyzed and detailed presented. And the correctness of theoretical analysis is verified by simulations. This study results can guide the selection...
This paper proposes a new wireless power transfer (WPT) control technique, which employs primary side controller and series-series (SS) or series-parallel (SP) compensation to achieve constant voltage (CV) charging or constant current (CC) charging without the information of the variable load. Through the variation of primary side resonant current, the charging voltage or charging current is estimated...
