摘要
提出一种新型的多端口输入的逆变器拓扑,可同时接入2路光伏发电单元和1路储能单元,并实现整个系统的模式切换和智能控制,解决了传统户用逆变器工作模式单一的问题,能满足更多用户的需求。在理论研究基础上,设计出了多端口逆变器的具体电力电子拓扑,并对硬件设计进行了大致介绍。说明了每个模块的控制策略和各个模块之间的协调控制策略,并给出控制框图。通过仿真和实验说明了提出理论的正确性和可行性。
A multi-port inverter topology is proposed,which can access 2 photovoltaic units and 1 energy storage unit simultaneously.And it can realize the mode switching and intelligent control of the whole system,solving the modeless problem of the traditional household inverter.So it can meet the more users.Basis on theoretical research,the topology of the multi-port inverter is designed,the design of the hardware is introduced.The details of the control strategy of each module and between modules are given,and the control block diagram is given.The correctness and feasibility of the theory are indicated through simulation and experiment.
