| 摘 要： | 随着大量电力电子开关器件的应用,传统的正弦稳态或准稳态假定在分析某些快速暂态问题上已经难以兼顾速度和精度。动态相量法模型在分析此类问题上比传统的稳态模型精确,非常接近时域仿真结果,适合快速数值仿真。本文对含电力电子开关器件的变换器用动态相量法建立了数学模型,通过对Buck-boost变换器中电感电流和电容电压时域仿真结果的傅里叶(FFT)分析,提出使用直流分量近似时域结果,从而又简化和改进了Buck-boost变换器的动态相量模型。仿真结果表明该模型具有非线性、时不变的特点,能准确反映变换器暂态过程。 |

| Abstract: | With the application of large number of power electronic devices,traditional sinusoidal steady-state or quasi-steady state assumption in the analysis of fast transient problem can't meet the requirements of both speed and accuracy.Dynamic phasors model used to analyze this problem is more precise than by traditional steady-state model,its simulation results are very close to that obtained by the time domain simulation,and its simulation is fast.In this paper,dynamic phasors method is used to build a mathema... |
