Superiority of BPF theory for design of coupled resonator WPT systems

A BPF design method is applied for WPT systems. It has been employed by the present authors mainly because it is clear, decisive and convenient. The present paper deals with the quality of the designed result. The operating bandwidth by the BPF design method has been made maximum with a certain coupling coefficient compared with other methods, which ensures a stable operation robust to the change of system parameters. In addition, the transmission loss is designed minimum by it, which is one of the most important features of the WPT system.
