摘要
本文作者提出了一种含储能的混合式配电变压器(Hybrid Distribution Transformer,HDT)电路拓扑,并重点研究了双向DC/DC变换器的设计。该拓扑结合储能电池和超级电容,通过双向DC/DC变换器实现HDT与储能装置之间的双向电能流动。本文推导了双向DC/DC变换器的小信号模型,详细阐述了电路参数选取方法,并设计了相应的控制器。在Matlab/Simulink中实现了仿真验证,结果表明所设计的系统能够实现功率的双向传递,验证了所提出拓扑和控制策略的有效性和可行性。
This paper proposes a hybrid distribution transformer topology incorporating energy storage,with a focus on the design of a bidirectional DC/DC converter.This topology integrates energy storage batteries and supercapacitors,enabling bidirectional power flow between the HDT and the storage devices through the bidirectional DC/DC converter.The small-signal model of the bidirectional DC/DC converter is derived,and the method for selecting circuit parameters is elaborated.Corresponding controllers are also designed.Matlab/Simulink simulations verify that the designed system can achieve bidi-rectional power transfer,demonstrating the effectiveness and feasibility of the proposed topology and control strategy.
