Analysis of power transfer characteristic of capacitive power transfer system and inductively coupled power transfer system

The capacitive power transfer (CPT) system and inductively power transfer (IPT) system are the two typical wireless power transfer systems. Based on the power transmission characteristics, the power transfer capacity of the two wireless power transfer system was analyzed. Firstly, the maximum power transfer capacity and its existing condition of the two types of wireless power transfer system were analyzed, and the choose gist of wireless power transfer system was presented according to the analysis result; then, the parameters of the two types of wireless power transfer system were optimized for achieving maximum power transfer; finally, the theoretical research was justified via a simulation.
