一种基于倍压单元的双输入高增益直流变换器
Dual Input High Step-up DC-DC Converters With Voltage Multiplier Cells
摘要
Abstract
According to the problems that more than one energy source, low output voltage of the battery module and unstable output power in the distributed photovoltaic power generation system, a dual input high step-up DC-DC converter with capacitor-diode multiplier cells was proposed in this paper. The proposed topology has the following advantages: the voltage gain is high, the voltage stress of the switches is low, there are more control freedoms and the sources can deliver power to the load with flexible power management methods. Firstly, the operation mode and the performance characteristics of the converter were presented in detail. Secondly, the steady state analysis, the voltage and current stresses of the switches and the relationship between the input currents were also introduced. Finally, the correctness and feasibility of the proposed circuit topology and the theoretical analysis were fully verified by a 1000W prototype.关键词
