摘要：

在新能源联合发电系统中,多输入直流变换器能够简化系统结构和降低成本,因而被广泛采用。针对现有的多输入直流变换器输出电压低、功率不稳定的问题,提出了一种新型双输入高增益直流变换器拓扑。从双输入直流变换器的工作原理出发分析变换器的工作特性,并计算在不同工作方式下的电压增益。不同模式下的MATLAB/Simulink仿真结果表明,该电路拓扑具有高升压比、电路拓扑简洁,且输入源可根据负载协调分配等优点。

Abstract:

In the new energy combined power generation system, the multi-input DC-DC converter can simplify the system structure and reduce the cost, therefore it is widely used. In order to solve the problem of low output voltage and unstable power of the existing multi-input DC-DC converter, a novel dual-input high-gain DC-DC converter topology is proposed. Starting from the working principle of the dual-input DC-DC converter, the operating characteristics of the converter is analyzed, and the voltage gain under different working modes is calculated. The simulation results of MATLAB/Simulink in different modes show that the circuit topology had the advantages of high boost ratio, simple circuit topology, and the input sources can be allocated coordinately according to the load.
