Analysis of rectangular EV inductive charging coupler (original) (raw)

2017, 2017 12th IEEE Conference on Industrial Electronics and Applications (ICIEA)

The number of commercial electric vehicles has increased significantly in recent years. However, there are still limited recharging facilities for EVs. Wireless charging offers an alternative way to recharge with more flexibility and convenience. The wireless transformer/coupler is the key component in electric vehicle wireless charging. The maximum power transfer capability is limited by the coupler. In order to reach desired power transfer level, the parameters of the wireless transformer should be analyzed. The wireless power transfer system design also requires accurate coupler parameters. In this paper, rectangular pads with different size of ferrite bars were analyzed in finite element analysis software. The prototype was built to valid the simulation result.
