Abstract：Multi-input Boost converters have the advantages of small size, low cost, high gain, and flexible control methods compared with Boost converters operating in a traditional parallel mode. Therefore, they have broad application prospects in new energy joint distributed power generation systems. However, due to the existence of multi-input voltage and power switches, the power supply mode and output ripple voltage of the multi-input Boost converter are more complicated than those of traditional Boost converters. In order to provide correct theoretical guidance for the analysis and design of the multi-input Boost converter, this paper studies the power supply mode and output ripple voltage of dual-input Boost converter with interleaved control. It is found that there are three energy supply modes for inductor L1: complete inductor energy supply mode (CISM), incomplete inductor energy supply mode (IISM) and discontinuous conduction mode (DCM), and two energy supply modes for inductor L2: continuous conduction mode (CCM) and DCM. The critical inductance of each energy supply mode is derived, and the analytical expression of output ripple voltage of each energy supply mode is obtained. Accordingly, the parameter design method of dual-input Boost converter is given. The experimental results verify the correctness of the theoretical analysis.
