中文摘要:
      全桥LLC变换器拓扑简单,易于实现所有开关管的软开关,被广泛应用于中大功率场合。针对全桥LLC变换器,建立了变换器的共模噪声模型,分析了共模噪声源和共模噪声耦合路径,提出了基于平衡电容的共模噪声抵消方法,并给出了变压器寄生电容参数的提取方法。最后通过实验验证了模型的准确性和方法的可行性。
英文摘要:
      Full-bridge LLC converter has been widely used in medium-to-high power applications because of simple topology and ease of achieving soft-switching for all power switches. The common noise model of full-bridge LLC converter is established. The common mode noise source and common mode noise coupling path are analyzed. The common mode noise cancellation method based on balance capacitor is proposed and the extraction method of parasitic capacitance for transformer is given. Finally, the correctness of the model and the feasibility of the method are verified by experiments.
