| 摘 要： | 由于四个线圈分时工作,应用于推挽变换器的变压器线圈交流损耗模型与线圈同时工作的高频功率变压器有很大不同.通过深入研究线圈电流谐渡磁势平衡特点,提出将一个四线圈分时工作的推挽变压器等效为两个独立的变压器,分别建立这两个变压器的谐波电流损耗模型,从而获得整个变压器的线圈损耗建模方法,并据此提出通过这两个等效变压器测量推挽变...

| Abstract: | Because of the four windings operating at time-sharing mode,AC winding model of push-pull transformer is different from the model of high-frequency power transformer with windings operating simultaneously.By the deep research on the MMF balance characteristics of the windings harmonic excitation currents,the new winding loss model was built for push-pull transformer.Based on the analysis,the total winding loss can be considered as the sum of the winding loss of two non-tapped forward-type transformers with ... |
