摘要

本文讨论了采用模块化全桥dc-dc变换器作为中间变换器的太阳能光伏(SPV)阵列馈电开关模式电源变换器(SMPC)。在不同类型的dc-dc变换器中，为了从SPV阵列获得最大的功率，选择了简单、简单的升压变换器。简化部件数的直接升压变换器具有最小化输出电流纹波和具有无界区域的最大功率点提取的固有特征。通过设计SPV阵列在额定直流电压下提供最大功率和最大开关利用率的升压变换器，实现了变换器效率的提高。阐述了该变换器的设计、分析和工作模式，并通过MATLAB/Simulink仿真对其性能进行了验证。

Design and analysis of solar photovoltaic array fed modular full-bridge DC-DC converter for 12 kW SMPC

This paper discusses the solar photovoltaic (SPV) array fed switched mode power converter (SMPC) using a modular full-bridge dc-dc converter as an intermediate converter. Among the different types of dc-dc converters, the straightforward and uncomplicated boost converter is selected in order to obtain the maximal power from the SPV array. The straightforward boost converter with reduced part count has inherent features of minimizing the output current ripples and possessing an unbounded region for maximum power point extraction. The improved efficiency of the converter is achieved by designing the SPV array to deliver maximum power at rated dc voltage and maximum switch utilization of the boost converter. The design, analysis and operating modes are explained for the proposed converter and the performance is validated through MATLAB/Simulink based simulation.
