| description | This paper presents a novel high-gain non-isolated Four Port DC-DC converter (FPC) topology for hybrid energy applications. The proposed four-port dc-dc converter interfaces four power ports of three input ports and one output port. High output voltage gain, minimized component count, and high efficiency are the advantages of the proposed converter, which renders it very useful for hybrid energy applications such as fast-charging electric vehicles. The high output voltage gain of the proposed FPC is achieved by the Actively Switched Inductor Capacitor (ALC) network. Moreover, the reduction in component count is achieved by minimizing the number of switches per input port. This enhances the converter efficiency is 96.77 % with a voltage gain 4.75. In this study, the FPC topology and modes of operation are described along with complete, steady state analysis, loss analysis, and switch voltage stress (VS) analysis of the converter. The converter operates in five modes, where all three sources can either be interfaced with the load by simply altering the switching patterns. Circuit topology, modes of operation, circuit analysis simulation, and real-time validations have been described in this paper. |
