ONE-CONTROL PERIOD STABILIZING METHOD OF CURRENT AND VOLTAGE OF ALTERNATING CURRENT HIGHER HARMONIC FILTER OF CURRENT PULSE WIDTH MODULATION SYSTEM CONVERTER

摘要

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.
