Dual input-dual output single inductor dc-dc converter

This paper presents a new single inductor Dual Input-Dual Output dc-dc converter for a standalone hybrid energy system. The converter has two unidirectional ports, one bidirectional port for storage element and one output port. The converter operates in dual input-dual output mode, dual input-single output mode and single input-single output mode. Both the input sources can power up the load individually and simultaneously. A single inductor is used with five independently controlled switches which make the size compact and easy to control. The analytical results in Continuous Conduction mode and simulation results in MATLAB/Simulink environment for different operating conditions are shown and are experimentally validated.
