| 摘要: |
| 分析了在单周期控制条件下三相高功率因数整流器的工作原理,并推导了三相PWM整流器的开关数学模型和等效控制方程。在建立此模型的基础上,基于庞加莱映射推导了三相PWM整流器工作时的稳定性条件及动态特性。应用仿真软件Saber在以上理论分析基础上完成了功率因数校正变换器建模与数字仿真,并进行了2kW三相PWM整流器的试验研究,详细研究了系统在负载变化或输入电压扰动等动态情况下的稳定性和动态特性,仿真和试验结果验证了理论分析的正确性。 |

| Abstract: |
| The operating principle of three-phase PFC(Power Factor Correction)rectifier under OCC(One-Cycle Control)is analyzed and the mathematic switching model and equivalent control equation for three-phase OCC-PFC are derived,based on which,its working stability conditions and dynamic performance are derived based on Poincare mapping.The modeling and digital simulation of PFC converter are implemented with Saber simulation software,and the experiments of 2 kW three-phase PWM rectifier are carried out.Its stability performance and dynamic performance under load change or input voltage disturbance are studied.Simulative and experimental results verify the theoretic analysis. |
