|A high-efficiency bidirectional buck-boost DC-DC converter|
This paper presents efficiency optimization and implementation of a bidirectional DC-DC converter based on the four-switch, non-inverting buck-boost configuration. The converter is intended for DC power systems to interface different sources or loads to a common DC bus, operating over a wide range of voltages. The number of converter phases, switching frequency, and inductor parameters are determined by an iterative efficiency optimization approach. The experimental 500W bidirectional converter operates from 12–38V at the source/load port to 21–32V at the bus port, with up to 97% efficiency.
