In practical dynamic electric vehicle (EV) wireless charging applications, the charging roadway is segmented and the segments are switched on and off along with the passing-by EVs, which often causes output power pulsations. Here, the decoupling characteristics of two general inductively coupled coils are investigated. Based on which, an easy-implement switching strategy to minimise the output power pulsation in the repeatedly occurring segmental switches is proposed. Each segment is to be… Expand
