建立了桥式变换器主电路开关器件附近的近场耦合模型,同时考虑高频寄生参数的影响,建立了开关器件组连线及其端子的近场辐射模型,构成了桥式变换器主电路开关附近辐射场的整体解析模型。所建模型及分析为功率变换电路内部强、弱电部分耦合的研究提供了依据和新的思路。
This paper proposes a model of near-field coupling of main circuit switch devices of bridge converter.Meanwhile,considering the effect of high-frequency parasitic parameter,the near-field radiation model of the wiring and terminals of switch device set is established,thus we get the complete analytical model of near-field radiation of bridge converter.The model and its analysis throw a new light on the future study of coupling of strong and weak electricity inside main circuit of power converter.
