Abstract

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.

Key words: new energy, combined power generation, multiple input, high gain, DC-DC converter, MATLAB
