Abstract
:1. Introduction
2. Theoretical Analysis
- The geometric parameters of the transmitter and the receiver coils are not changed; hence, the circuit parameters are also unchanged and are given as constants.
- The resonant compensated capacitance values of the transmitter and receiver are given as constants.
- The resonant frequency of the transmitter and receiver is equal to the frequency of the high-frequency inverter.
