Title:
DC POWER SOURCE CIRCUIT
Document Type and Number:
Japanese Patent JP2637646
Kind Code:
B2
Abstract:

PURPOSE: To reduce the higher harmonic components by removing the pause division of an input current, and at the same time, to lower the voltage applied to an inverter.
CONSTITUTION: In a DC power source circuit which is so arranged as to apply the full wave rectified voltage of a full wave rectifying circuit 2 to load 3, being equipped with said full wave rectification circuit 2 which rectifies the full waves of an AC power source 1, a diode 5 is connected, in series in the direction of checking a reverse flow, between the full wave rectification circuit 2 and the load 3, and a capacitor 6, which is charged to be of reverse voltage to the diode 5, is connected in parallel with the diode 5 through a switch 19 which is turned on or turned off in the same phase.
