摘要
基于主动功率因数校正加谐振变换器的传统两级式电源,提出了一种交错并联的谐振变换器(LLC)。在大功率电动汽车车载电源中,该方案可有效降低器件电流应力,提高功率等级,并降低输出纹波。最后通过对谐振全桥变换器的纹波计算,证明该方案在降低输出纹波上的有效性。
This paper presents an interleaved resonant converter（LLC） based on the traditional two stage charger with active power factor correction and resonant converter.It is suitable for the electric vehicle onboard charger,having the advantages of reducing current stress,increasing the power level,and reducing the ripple.The topology is proved efficient in reducing the ripple by calculating the ripple of the resonant full bridge converter.
