RECTIFIER
Document Type and Number:
Japanese Patent JPS59122377
Kind Code:
A
Abstract:
PURPOSE:To reduce the harmonic wave of an input current and a reactive current by controlling a current flowed from a single phase AC power source to a reactor via a switching element and rectifying it. CONSTITUTION:A series circuit of a reactor 11 and a switching element 12 is connected between single phase AC input terminals 1 and 2. A series circuit of diodes 13, 14 and capacitors 15, 16 is connected between both terminals of the switching element 12. A DC output voltage is generated between the output terminals 3 and 4 by controlling ON or OFF the element 12 via a controller 22. The controller 22 is composed of a multiplier 23, a level detector 24, an output voltage reference value, an adder 26 and a voltage controller 27.
