摘要
对共直流母线的非隔离全桥可控电流源逆变器交错并联的几种控制策略进行了分析比较。分析了载波交错单极性倍频控制下电感电流的谐波构成,根据工作模态推导了该逆变器在交错并联状态下单个电感电流的最大脉动量表达式,并对比了不交错与交错情况下的脉动差异,为电感优化设计提供了指导。最后通过仿真和实验验证了分析的正确性。
In this paper, several control strategies of the non-isolated interleaved parallel full-bridge controllable current source inverter with a common DC are analyzed and compared with each other. Analysis of the harmonic structure of the inductor current under the control of carrier-based interleaved unipolar frequency-doubling SPWM is carried out. Thus the maximum ripple of a single inductor current within the converter is figured out in the interleaved condition according to the operating mode, and then compared with that in the synchronized condition. This provides a guideline for the design of the inductor. The simulation and experiment are carried out to verify the correctness of the analysis.
