【Abstract】 This paper presents a new nonlinear impedance transformation tache with inductance ,varied with the voltage.It can be used in front of the filter tache with capacity in general bridge rectifier circuit and ensure that when the voltage of power supply is lower than the rectifier voltage the value of nonlinear impedance will vary with it.Consequently the range of dead area of input current will be hurdled and reduced efficiently.At the same time the harmonious wave was reduced and the character of power factor was improved.更多还原
