Resonant converters with a wide input range are much in demand in energy storage and new energy systems. When the voltage gain characteristics of an LLC resonant converter are calculated using the operation mode analysis (OMA) method, it is often assumed in previous studies that the circuit under phase shift control is in discontinuous conduction mode, resulting in significant errors in the gain analysis result of a converter which is in continuous conduction mode. On the basis, an OMA calculation method for an LLC resonant converter with a voltage doubling rectifier is proposed to identify the two modes. First, the criterion for determining whether the converter operates in continuous or discontinuous conduction mode is obtained through the modal analysis. Then, the normalized calculation models of these two modes are derived by OMA, and the calculation results and the criterion are used to verify the actual mode. Finally, a comparison among the calculated, simulated and experimental voltage gain curves under different conditions indicates the effectiveness of the proposed method. This method is more applicable to LLC converters in possible continuous mode, improves the accuracy of the gain analysis and is helpful for parameter design.

宽输入谐振变换器在储能与新能源系统中有广泛的应用需求。应用时域分析法求取LLC谐振变换器的电压增益特性时,已有研究通常假定移相控制电路处于电流断续模式,使得变换器连续模式的增益分析结果出现明显误差。针对倍压整流LLC谐振变换器,提出识别2种模式的时域分析计算方法。首先通过模态分析得出电流连续或断续的判据;然后以时域分析法推导2种模式的归一化计算模型,并使用计算结果和判据验证工作模式;最后通过不同条件下电压增益曲线的计算、仿真和实验对比证明了所提方法的有效性。结果表明,该方法对可能出现连续模式的LLC变换器更加适用,增益分析的准确性有所提高,有助于参数设计。

宽输入谐振变换器在储能与新能源系统中有广泛的应用需求。应用时域分析法求取LLC谐振变换器的电压增益特性时,已有研究通常假定移相控制电路处于电流断续模式,使得变换器连续模式的增益分析结果出现明显误差。针对倍压整流LLC谐振变换器,提出识别2种模式的时域分析计算方法。首先通过模态分析得出电流连续或断续的判据;然后以时域分析法推导2种模式的归一化计算模型,并使用计算结果和判据验证工作模式;最后通过不同条件下电压增益曲线的计算、仿真和实验对比证明了所提方法的有效性。结果表明,该方法对可能出现连续模式的LLC变换器更加适用,增益分析的准确性有所提高,有助于参数设计。

Resonant converters with a wide input range are much in demand in energy storage and new energy systems. When the voltage gain characteristics of an LLC resonant converter are calculated using the operation mode analysis (OMA) method, it is often assumed in previous studies that the circuit under phase shift control is in discontinuous conduction mode, resulting in significant errors in the gain analysis result of a converter which is in continuous conduction mode. On the basis, an OMA calculation method for an LLC resonant converter with a voltage doubling rectifier is proposed to identify the two modes. First, the criterion for determining whether the converter operates in continuous or discontinuous conduction mode is obtained through the modal analysis. Then, the normalized calculation models of these two modes are derived by OMA, and the calculation results and the criterion are used to verify the actual mode. Finally, a comparison among the calculated, simulated and experimental voltage gain curves under different conditions indicates the effectiveness of the proposed method. This method is more applicable to LLC converters in possible continuous mode, improves the accuracy of the gain analysis and is helpful for parameter design.
