ABSTRACT:
A pulse width modulation inverter is controlled by the use of the fundamental wave voltage E.sub.1 of the inverter output as a feedback quantity, the fundamental wave voltage E.sub.1 being obtained as the product of a function g(K.sub.H) which is determined by the amplitude ratio K.sub.H of a carrier wave and a modulated wave, and a d.c. voltage E.sub.D input of the inverter.
