中文摘要:

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。

英文摘要:

Modeling and analysis of single phase inverter are usually based on integer order calculus, regardless of the fractional characteristics of inductors and capacitors. This approximate will bring a deviation with the real system. Aiming at this problem, this paper analyzed the behaviors of the fractional order capacitors and fractional order inductors and proposed the fractional model of single phase voltage type inverter. 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 model is more accuracy to simulate the real system.
