摘要：

This paper presents a novel idea to enhance the switching of power electronic converters used for driving closely spaced multi-transmitter (MT) wireless power transfer (WPT) systems. Cross coupling amongst the transmitters is an undesirable phenomenon for power electronic converters as they induce an spurious voltage in the adjacent coils. Therefore, with the use of coupled inductors (CPIs) a new method to mitigate the effects of cross couplings is proposed. To study the effect of CPIs on soft switching, an MTWPT system consisting of three transmitters and one receiver is used as a case study. The system is mathematically analysed, numerically simulated, and experimentally tested, and the results validate the efficacy of the proposed approach.
