Abstract:

传统的桥式LLC谐振变换器不适合宽电压范围输入,且其输入电流断续。为此提出了一种新型的Boost型LLC谐振变换器。通过集成两个交错并联的Boost电感,不仅可以拓宽LLC变换器的增益范围,而且可以显著减小输入电流的纹波,因此该变换器适合用在光伏、燃料电池等可再生能源发电系统中。与传统的脉冲频率调制控制相比,该变换器采用定频脉冲宽度调制控制,励磁电感和Boost电感对变换器的增益特性影响很小,可以简化谐振参数的设计,同时定频控制也有利于磁性元器件和滤波电路的设计。首先介绍了该变换器的工作原理;然后通过时域分析,对该变换器的增益特性进行了深入研究;之后对变换器的ZVS软开关条件进行了详细的分析;最后建立了一台120~240V输入、24V/25A输出的实验样机,实验结果验证了变换器的实用性及理论分析的正确性。
