单相逆变器分数阶建模及分析
目前单相逆变器的建模分析以整数阶理论为基础,未考虑电感、电容的分数阶特性,与实际系统有一定误差。针对此问题,本文首先分析了分数阶电感和分数阶电容的特性,在此基础上建立了单相全桥电压型逆变器的分数阶模型,并对比分析了整数阶模型和分数阶模型的差异。结果表明:整数阶模型与实际系统的偏差为9.38%,分数阶模型与实际系统的偏差可控制在1.56%,分数阶模型能够更准确的描述实际系统特性。...

Bibliography: | 23-1202/TH Modeling and analysis of single phase inverter are usually based on integer order calculus theory,regardless of the fractional characteristics of inductors and capacitors,which will bring a deviation with the real system. Aiming at this problem,this paper firstly analyzed the behaviors of the fractional order capacitors and fractional order inductors,and on this basis,the fractional order model of single phase full bridge voltage type inverter was proposed. Then,the differences between integer model and fractional model about the inverter are compared. The results show that the percentage error in the integer model and the fractional model is 9. 38% and 1. 56% respectively. In other words,the fractional order model is more accurate to simulate the real system.
