PURPOSE: A power supply apparatus for feeding power with large capacity is provided to minimize power loss by using direct current. CONSTITUTION: A rectifier(210) converts alternating current(202) into direct current. A direct current transmission line(220) transfers the direct current generated from the rectifier to a converter(230). The converter transfer voltage to an inverter unit(240). The converter includes a capacitor(Cdc), a switch(Q1), an inductor(Lb), and a diode(D). A smoothing capacitor(Cb) removes noise. [Reference numerals] (A1,A2,A3,B1,B2,B3,C1,C2,C3) Feeding segment |
