Title:
INVERTER DEVICE
Document Type and Number:
Japanese Patent JP3163657
Kind Code:
B2
Abstract:
PURPOSE: To eliminate discontinuous input current, and reduce harmonic component of input current.
CONSTITUTION: In an inverter device provided with a circuit for electrifying input current from an AC power source Vs via an inductor, an inverter element, and a switching element and improving an input power-factor, a means for suppressing voltage V3 to be generated in the direction to be superposed on the rectified output voltage of a full-wave rectifier DB on an inductor L1 to be included in the inverter element is set, regardless of conditions to be controlled. Accordingly, discontinuous input current is eliminated, and the harmonic component can be made less.
