Abstract Hybrid power systems derive power simultaneously from several renewable energy sources and deliver power continuously to the load. For such systems, the use of a multiple-input converter (MIC) has the advantage of simpler circuit design and lower cost. The hybrid power system with a MIC is a typical multiple-input and multiple-output coupled system, so the closed-loop design is very complicated. In this paper, a novel three-input Buck, Boost, Buck-Boost converter is taken as an example, decoupling control will be inserted to the system and the regulator can be designed respectively. Static and dynamic permanence will be enhanced. Experimental results are given to verify the design effectiveness with a 400W prototype. This method can be applied to the other three-input DC-DC converters.
