A new efficient rectifier based on nonlinear inductance impedance transformation

在对常规整流电路的输入特性分析的基础上,提出设计了一种基于电感非线性阻抗变换的环节,并应用到常规桥式整流电路的电容滤波环节前,保证当电源电压低于整流直流电压时,使非线性阻抗值也随之发生变化,来有效地克服和缩小输入电流的死区范围,减少谐波含量,从而改善了系统的功率因数品质,对于电力节能具有重要的意义。

A new nonlinear inductance impedance transformation circuit is presented based on the the characteristics of general rectifier circuit. Before being used in capacitance filter of the general bridge rectifier and it ensures that when the power voltage is lower than that of rectifier the value of nonlinear resistance will vary with the voltage to check the dead area range for input current and decrease harmonics. It improves the character of power factor, and is important to energy saving.
