PROBLEM TO BE SOLVED: To simplify a control apparatus for converting an AC input current waveform of the rectifying power supply to a sine wave. SOLUTION: A control apparatus is formed using a current feed forward control method for injecting an information SI corresponding to the peak value of an input current sensed with DCCT to a control loop of a rectifying power supply output, an error amplifying circuit D1, a pulse converting circuit D2 and a semiconductor switch Q to form a constant voltage feedback control circuit of an output DC voltage.
