A Review of Bidirectional Resonant Converter
This paper provides a comprehensive review of various dc dc converter topologies such as Pulse Width Modulation converter, hybrid resonant converter, Dual Active Bridge converter, Series and parallel LLC resonant converter. The confusion takes place while selecting a converter as every converter has its merits and demerits. In this paper, detailed description and classification of the resonant converters have made based on the features and its applications. Among all the resonant converters the LLC resonant converter has become more popular due to its special features like wide range of soft switching capability, better efficiency, reduced reverse energy and high power density. By using the new control scheme in the LLC converter by adjusting the power angle between input and output side, the power flow direction and output power of the converter can be changed automatically and continuously, which is attractive for energy storage systems to balance the energy. This review paper is intended to serve as a convenient reference to future resonant converter users.
