Abstract
:1. Introduction
2. Fundamental Analysis
2.1. The SS Compensation Circuit
2.2. The SP Compensation Circuit

3. Simulation
4. Experimental Evaluation
- (a)
- The simulation model, built in an ideal circumstance, has less power loss than the actual circuit.
- (b)
- The electromagnetic shielding effectiveness of the ferrite core, which is made of small blocks, is worse than the whole ferrite core built in Maxwell.
- (c)
- There are measurement error and other extraneous factors affecting the transmission efficiency.
