Single-stage multi-port DC-DC converter topology

A single-stage multi-port DC-DC converter topology is proposed. It can accommodate arbitrary number of input sources and output loads, and employs a single inductor. The voltage of each output port can be less than the minimum input voltage or exceed the maximum input voltage. Power regulation can be provided for the input ports in addition to providing voltage regulation for the output ports. The steady-state and dynamic characteristics of the converter are analysed and a control scheme is proposed. Hardware measurements and numerical switch-level simulations verify the analytical results.
