介绍了一种新型级联式BuckBoost变流器，并对其进行了建模与理论分析。在确定变流器工作原理的基础上，通过详细的分析建立了变流器的开关函数模型，接着推导了变流器的开关周期平均值模型。该模型表明了该变流器系统具有双向能量流动和升降压的能力，并揭示了该变流器在控制上具有较强优势的原因在于它有一个额外的控制自由度。最后通过实验验证了上述分析。

The modeling and theoretical analysis of a new bi-directional buck-boost cascade inverter was introduced. The switching function model was established based on the operation principle of the proposed inverter. Then, the averaged model for control purpose was given. The inverter was proved to be the bi-directional and buck-boost capability. The control superiority of the inverter was attributed to its extra control freedom. Finally, the experiments verified the analysis.
