Under the traditional phase disposition (PD) modulation strategy, there is a power imbalance problem among the units in a cascaded H-bridge inverter. Aimed at this problem, the control principle of freedom degrees is analyzed, and a novel power equalization modulation strategy is proposed. On the basis of ensuring the output power equalization and voltage harmonic characteristics, the power equalization time is shortened, and the complexity in digital control is reduced. On the one hand, the freedom degrees of triangular carriers are recombined based on the PD modulation method to distribute them evenly in different carrier layers. Then, by fully utilizing the switching redundancy state at each output level, the power equalization is achieved within a carrier cycle to shorten the time needed for achieving the equalization. On the other hand, the complexity in digital control is reduced by restructuring the vertical freedom degree of the modulated wave. Finally, the theoretical analysis and feasibility were verified by simulation and experimental results.

针对级联H桥逆变器在传统的同相层叠PD(phase disposition)调制策略下,各单元之间存在功率不均衡问题,深入分析自由度控制原理,提出1种新型功率均衡调制策略,在保证输出功率均衡和电压谐波特性的基础上,缩短功率均衡时间,降低数字控制复杂度。该方法一方面在PD调制法的基础上对三角载波进行自由度重组,让其均匀分布于不同载波层间,充分利用各输出电平的开关冗余状态,使其在1个载波周期内实现功率均衡来缩短均衡所需时间;另一方面,对调制波垂直自由度进行重组,以降低数字控制的复杂度。最后通过仿真和实验对理论分析及可行性进行验证。

针对级联H桥逆变器在传统的同相层叠PD(phase disposition)调制策略下,各单元之间存在功率不均衡问题,深入分析自由度控制原理,提出1种新型功率均衡调制策略,在保证输出功率均衡和电压谐波特性的基础上,缩短功率均衡时间,降低数字控制复杂度。该方法一方面在PD调制法的基础上对三角载波进行自由度重组,让其均匀分布于不同载波层间,充分利用各输出电平的开关冗余状态,使其在1个载波周期内实现功率均衡来缩短均衡所需时间;另一方面,对调制波垂直自由度进行重组,以降低数字控制的复杂度。最后通过仿真和实验对理论分析及可行性进行验证。

Under the traditional phase disposition (PD) modulation strategy, there is a power imbalance problem among the units in a cascaded H-bridge inverter. Aimed at this problem, the control principle of freedom degrees is analyzed, and a novel power equalization modulation strategy is proposed. On the basis of ensuring the output power equalization and voltage harmonic characteristics, the power equalization time is shortened, and the complexity in digital control is reduced. On the one hand, the freedom degrees of triangular carriers are recombined based on the PD modulation method to distribute them evenly in different carrier layers. Then, by fully utilizing the switching redundancy state at each output level, the power equalization is achieved within a carrier cycle to shorten the time needed for achieving the equalization. On the other hand, the complexity in digital control is reduced by restructuring the vertical freedom degree of the modulated wave. Finally, the theoretical analysis and feasibility were verified by simulation and experimental results.
