电容滤波的单相不控整流器输入阻抗特性研究
Research on Input Impedance Character of Single-phase Uncontrolled Rectifier with Capacitor Filter
摘要
Abstract
The input impedance is an important parameter in the stability analysis of system with uncontrolled rectifier by using impedance stable criterion. A new study method for input impedance character of rectifier was proposed. Firstly,the boundary condition of single-switching and multi-switching of diode at half of line voltage period was analyzed. And on this basis,the input impedance model of uncontrolled rectifier was developed in a wide frequence. The theoretical analysis and the simulation results show that the input impedance of uncontrolled rectifier is resistance-capacitance,and the input impedance of uncontrolled rectifier is related to the load in DC side.关键词
