METHOD AND SYSTEM FOR CONTROLLING OUTPUT VOLTAGE OF PULSE WIDTH MODULATION INVERTER

摘要

A pulse width modulation inverter is controlled by the use of the fundamental wave voltage E1 of the inverter output as a feedback quantity, the fundamental wave voltage E1 being obtained as the product of a function g(KH) which is determined by the amplitude ratio KH of a carrier wave and a modulated wave, and a d.c. voltage ED input of the inverter.
