Analysis and design of a bidirectional DC-DC converter with current doubler rectifier used in Smart Grid
Distributed generation systems convert energy from solar panels, wind turbines, fuel cells etc. and supply DC/AC buses with energy of improved quality. The article describes the analysis and design of a mixed topology consisting of a phase shift converter responsible for transferring energy from the DC bus to the storage elements, and an interleaved boost converter responsible for transferring energy from the storage element to the DC bus. A new method for controlling the reverse transfer mode is developed. Also a new method for the determination of the transfer functions of the converter will be presented.
