Abstract Multilevel voltage-balancing DC-DC converter (MVBDC) shows good application prospect in medium and high voltage DC conversion field. However, with the increase of output levels, the resonant current may introduce large input current ripple, which affects the converter efficiency and device life. This paper takes coupling and decoupling MVBDC as examples to analyze the relationship between MVBDC input current ripple and resonance currents at various levels, and the input current ripple suppression strategy is proposed. By controlling the phases of the resonant currents, zero ripple of the MVBDC input current can be achieved, which improves the converter efficiency. Finally, the correctness of the above theory is verified by experimental results.
