A Bipolar Current Source Power Resonant DC-DC Converter

A novel bipolar current source power resonant converter is proposed in this paper, which improves the performance of conventional series resonant converter (SRC) and parallel resonant converter (PRC). The current transfer gain is derived by making use of classical AC analysis. It implies that the proposed converter integrates the advantages of SRC and PRC, while overcoming their drawbacks. Furthermore, various switching subintervals and the corresponding equivalent circuits under discontinuous operating mode are also investigated. Finally, the simulative results confirmed the validity of the theoretical analysis.
