The actual duty cycle of a single-stage Buck converter is affected by the switching speed and dead time, so it is difficult to meet the wide range of voltage regulation applications. On this basis, a multilevel cascade Buck topology is adopted, and an output voltage cooperative control strategy for multilevel cascade converters is proposed. This control strategy takes into account the operation efficiency, and it adopts a hybrid modulation method combining pulse width modulation and frequency conversion modulation, thus realizing the output voltage control switching at all levels of the converter and covering the full range of output voltage. A switching loss model is established, and the efficiency optimization under hybrid modulation is analyzed. Finally, a simulation model was established to verify the correctness of the modulation and control design, and an 8 kW two-stage prototype with 50–75 V input and 1–40 V/200 A output was built to verify the feasibility of the proposed control strategy.

单级Buck变换器的实际占空比受到开关速度与死区影响，难以满足宽范围调压需求。采用多级级联Buck拓扑结构并提出1种适用于多级级联变换器的输出电压协同控制策略。所述控制策略兼顾运行效率，采用脉宽调制与变频调制结合的混合调制方法，实现各级变换器输出电压控制切换并覆盖全范围输出电压。建立开关损耗模型并分析混合调制对效率的优化效果。最后搭建仿真模型验证调制与控制设计的正确性，并搭建了1台50~75 V输入，1~40 V/200 A输出的8 kW两级式样机验证所提控制策略的可行性。
