Abstract

A novel analytical method suitable for coupled electromagnetic field of a circuit is proposed in this paper. In a high frequency circuit and high-frequency converter, skin effects are obvious, and the variations in resistance and inductance values depend on frequency. In addition, the voltage and current distribution changes of a high frequency circuit generated with a high-frequency converter during dynamic switching process are complicated and depend on time. A novel analytical method suitable for coupled electromagnetic field of circuit in parameter optimization design of high-frequency circuit and high-frequency converter is proposed in this paper. The proposed method considers the influence of skin effect and coupled electromagnetic field on parameter variation simultaneously. According to the law between parameter variation and line length, the calculation process of parameter optimization will be simpler and more effective.
