Abstract

In this paper, dynamic analysis of a current source ICPT system is performed based on the circuit equations of each stage in an operation cycle. From the solution, frequencies of different stages are discussed. Besides a common frequency of the circuit, the other two are resonant frequencies of each side of the transformer. A simplified form of frequency expression is obtained. It is found that in certain circumstance, the resonant frequencies of primary and secondary sides are different and depend on elements of their respective sides. Some suggestions about the parameter selection are provided. The analytical analysis and considerations are verified by a practical ICPT system
