Method of controlling pulse width modulated inverter for use in induction motor drive |
摘要 |
An amplitude ratio KH of a specific level of a modulating wave and a crest value of a carrier wave is introduced into control of a pulse width modulated inverter, and a desired pulse width modulating signal is calculated by a microcomputer, using the amplitude ratio KH as a control variable.
