Abstract
There is a growing demand for multi-port power converters for managing multiple energy sources and loads. To that end, a dual-input single-output dc-dc converter is proposed in this article. The converter integrates two different and low-voltage dc sources into a dc bus. Pulse width modulation is used to control the transfer energy from the input ports to the output port. The discontinuous conduction mode (DCM) operation of the converter has enabled the soft-switching operation in the primary switches. Moreover, it helps avoid the high-frequency transformer (HFT) saturation when the two input voltage sources have different values. The detailed analysis of the proposed dc-dc converter is presented in this article along with the simulation and experimental results obtained from a 150 W hardware prototype to validate its operation.
