摘要
在具有多个新能源输入的联合供电系统中,一个多输入直流变换器(MIC)就可以实现传统的多个单输入直流变换器的功能,并且达到简化系统结构、降低系统成本的目的。MIC通常需要进行能量管理以实现可再生能源的优先利用。首先将多输入直流变换器系统和单输入直流变换器系统进行了比较,然后以双输入Buck变换器为例,分析了双输入Buck变换器工作原理。为了验证双输入Buck变换器工作原理的正确性,在Matlab中搭建了基于太阳能与市电互补的双输入Buck变换器仿真模型,对系统进行了仿真分析。仿真结果验证了双输入Buck变换器工作原理和能量管理策略的正确性。
In hybrid power systems of multiple inputs, a multiple-input converter（MIC） could realize the function which was realized by traditional single-input converters, which could simplify structure and lower cost of the system.Usually, the MIC needed to conduct power management to realize the priority use of the renewable energy. Two hybrid power systems were compared. Then the principle of the circuit of a double-input Buck converter system was analyzed. The simulation model of the double-input buck converter of the system combined by solar cell and commercial power was built, and simulation was conducted. The simulation results verify the correctness of the principle and power management strategy of the double-input buck converter.
