Title: Controller for rectifier
Inventor: MUTO NOBUYOSHI
IPC: H02M7/06
Filed: 1986-05-26
Abstract: PURPOSE:To improve the power factor of an AC input current efficiently even in a light load range by supplying a current proportional to the amplitude of a load to the output of a diode bridge circuit, and supplying an AC input current of power factor=1 to a power supply side even if the load is varied. CONSTITUTION:A load current is detected by a current detector 80, its output is input through a filter 90 to a reference voltage generator 140. The generator 140 generates a reference voltage which varies proportionally to the amplitude of a load. When the load 70 varies, the reference voltage varies in response to the variation to generate a deviation from a DC voltage from an F/V converter 120. A switching element 33 operates in response to the deviation. Thus, a current proportional to the amplitude of the load is fed to the output of a diode bridge 20. Since a load current is controlled to synchronize with the AC input voltage, even if the load varies, an AC input current of power factor=1 is always supplied to a power supply side.
