METHOD AND SYSTEM OF PULSE-WIDTH MODULATION (PWM) CONTROL FOR VOLTAGE POWER SUPPLY INVERTER MINIMIZING CURRENT SAMPLING ERROR AT ELECTRIC DRIVE

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for controlling an inverter which minimizes current sampling errors in an alternating-current motor drive.;SOLUTION: The method of controlling alternating-current (AC) motor includes a step for selecting a pulse sequence, based on the ripple current of instantaneous sampling in the AC motor of sampling, and a step for supplying a voltage to the AC motor, based on the pulse sequence.;COPYRIGHT: (C)2008,JPO&INPIT
