Abstract
Aiming at the influence of dead time setting on transfer power rating and efficiency of the inverter of double sided LCC resonant wireless charging transfer (WPT) system,a dead time optimization method for metal-oxide semiconductor field effect transistor (MOSFET) soft switching is proposed.First,the mathematical description of the double sided LCC resonant wireless charging system is established,and the operating mode is briefly analyzed as well.The quantitative characteristic is deduced that the secondary side compensation capacitor can be adjusted to ensure that the circuit is inductive.And a dead time optimization design method is proposed to realize zero voltage switching (ZVS) of the inverter that is closely related to the performance of the WPT system.Finally,a prototype is built.The experimental results verify that dead time calculated by this optimized method can ensure the soft switching of the inverter MOSFET,and promote the wireless power transmission power and efficiency.关键词
