【 摘 要 】

In this paper, a new transition regulation method (TRM) for three-level DC-DC converters is proposed. The conventional asymmetrical control for three-level DC-DC converters induces imbalanced currents in components, and the imbalanced loss would lead to characteristic variation which is harmful to the converter’s reliability. The proposed TRM strategy is analyzed and derived in this paper, and the circuit balance of the TRM is compared with conventional control methods. Finally, a prototype is implemented to verify the feasibility of the TRM, and the equalized operation current and loss of components can be verified by the experimental results.
