High-voltage and high-power stabilized DC power supply using modified sine wave output 3-phase inverter
 A stable DC power system of high-voltage and good-output performance is provided by adding a 3-phase inverter, whereby modified waveform for an output control is produced and a filter to a conventional DC power system and by bridge-rectifying. The modified sinusoidal wave such as a varied wave whose upper portion ranging from 30.degree. to 150.degree. is flat of a 1/2 cycle of the sinusoidal wave, a modified wave whose portions ranging from 30.degree. to 90.degree. and from 90.degree. to 150.degree. are linear in a 1/2 cycle of the sinusoidal wave and a modified wave whose portions ranging from 30.degree. to 90.degree. and from 210.degree. to 270.degree. are recessed so as to be symmetrical with respect to a line in the whole cycle of the sinusoidal wave are used for reducing ripples of the output voltage after the 3-phase rectification.
