Abstract:

在可再生能源联合发电系统中,采用单个多输入直流变换器(MIC)代替原有的多个单输入直流变换器,可以简化电路结构,降低系统成本。MIC通常需要进行能量管理以实现可再生能源的优先利用,因此采用MIC构成的可再生能源联合发电系统是一个典型的多输入-多输出的耦合系统,其闭环设计复杂。因此本文针对双输入Buck变换器,提出单周期控制方式来消除环路之间的耦合。同时本文还提出了模式切换电路以实现各个模式之间的平滑切换,并推导了双输入Buck变换器在不同工作模式下的单周期控制小信号模型。由该小信号模型可知,采用单周期控制无需电流调节器,而且电压调节器在不同工作模式下的设计条件相同,因此调节器的设计大大简化。最后本文设计制作了一台800W的实验样机,实验结果验证了所提出单周期控制方法的有效性。
