Abstract

Alternative energy sources like photovoltaic, fuel cell, wind, ultra capacitor, etc., are widely used in many applications such as in hybrid vehicles, micro grids etc. Combining two or more sources effectively, provides reliable power for the required application. Hence, the concept of hybrid energy system arises. In hybridization of energy systems, conventional sources and non-conventional sources are interfaced efficiently to drive the load. Two or more sources can be interfaced using different power electronic converters. Multiple Input DC/DC Converters (MIC) are one of the interfacing circuits used for hybridization of renewable and storage energy sources. In this paper, Dual input DC/DC converter is proposed which is useful in supplying the load from renewable and storage energy sources individually or simultaneously by connecting the two input sources in series. The two input sources to the converter used are photo-voltaic (PV) cell and a lead acid battery. Operation can be based on Buck, Boost or Buck-Boost modes. Using MATLAB/Simulink software, proposed converter is simulated.

混合能源系统双输入DC/DC变换器建模

光伏、燃料电池、风能、超级电容器等替代能源广泛应用于混合动力汽车、微电网等领域。有效地结合两个或多个电源，为所需的应用提供可靠的电源。因此，混合能源系统的概念出现了。在混合动力系统中，常规电源和非常规电源被有效地连接起来驱动负载。两个或更多的源可以使用不同的电力电子转换器进行接口。多输入DC/DC转换器(MIC)是用于可再生能源和存储能源混合的接口电路之一。本文提出了一种双输入DC/DC变换器，可将可再生能源和储能能源分别或同时串联起来供电。所使用的转换器的两个输入源是光伏电池和铅酸电池。操作可基于Buck、Boost或Buck-Boost模式。利用MATLAB/Simulink软件对所提出的变换器进行了仿真。
