REVIEW ON DC-DC POWER CONVERTER TOPOLOGIES AND CONTROL TECHNICS FOR HYBRID STORAGE SYSTEMS

Hybrid storage systems combine advantages of the different energy storage technologies, such as lithium-ion batteries and supercapacitors. Bidirectional power converters are dedicated to interface storage units to the grid and ensure bidirectional power flow. Proper control and energy management technics have to be applied to ensure efficient and optimal power distribution in the hybrid energy storage. In this paper, a review of bidirectional dc-dc converter topologies relevant to hybrid energy storage, including non-isolated, isolated, and interleaved topologies has been presented. Several control strategies including current-mode control, power control, and sliding mode control have been reviewed.
