PROBLEM TO BE SOLVED: To provide a method for suppressing transition vibration at high speed and improving the control of the effective power and reactive power of direct current output voltage and alternating current side.;SOLUTION: The instantaneous values of the reactor current is of a higher harmonic filter and capacitor voltage vc comprising a reactor and a capacitor provided on the alternating current side of the current pulse width modulation system converter of a single phase or three phases are controlled by the pulse width of the input current ix of the converter generated in a one-control period and its generating timing, and stabilized after the one-control period.;COPYRIGHT: (C)2002,JPO
