This paper proposes a non-isolated bidirectional DC-DC converter for energy storage systems. On the battery side, two sets of coupled inductors are used to achieve high voltage gain and reduce current ripple on the low-voltage side.
1. Introduction ty of bidirectional energy transfer between two dc buses. Apart from traditional application in dc motor drives, new applications of BDC include energy storage in renewable energy systems, fuel cell energy systems, hybrid electri
The system not only converts DC storage energy to the loads or the grids bidirectionally, but also supplies high quality power, such as low total harmonic distortion (THD) current to the girds or the load consumers, or low ripple charging current to the energy storage units.
The essential features and principles of the portable bidirectional energy storage converter proposed in this paper, which is based on a second-order generalized integrator phase-locked loop, are theoretically investigated. Formulas are also generated using small signals to address this issue.
