摘要
为解决临界导通模式(CRM)LCL谐振结构后接整流桥引入的等效电感计算较为困难的问题,提出了一种交流侧接临界导通模式LCL谐振变换器的整流电路功率因数计算方法。首先,在分析CRM LCL谐振变换器下整流桥的工作状态的基础上,采用微分方程建立了LCL谐振变换器的输入电压、电流的数学模型,并利用LCL谐振变换器并联谐振电容的基波电压值对其实际电压值进行了近似处理;然后,对所提出的方法进行了实验验证。实验结果表明:所提方法可以较为准确地计算交流侧接临界导通模式LCL谐振变换器时整流电路的功率因数。
In order to solve the equivalent inductance calculation problem caused by rectifier of AC side-connected LCL resonant converter,apower factor calculation method for the rectifier of AC sideconnected LCL resonant converter is proposed.Based on the analysis of the working state of the rectifier which connects the critical conduction mode（CRM）LCL resonant converter,a mathematical model of the input voltage and current of the LCL resonant converter is proposed in the form of differential equation.And the fundamental voltage value of the parallel resonant capacitor of the LCL resonant converter is used to approximate its actual voltage value.Finally,experimental verification is carried out.The experimental results show the proposed method can be used to calculate the power factor of the rectifier of AC side-connected CRM LCL resonant converter.
