Abstract

The purpose of this paper is to show a high performance digital control technique of single phase inverters with internal state feedback. The study proves that the high speed processor allows an excellent output signal waveform, even in critical conditions. The reduced computational effort is an attractive feature. That is obtained by using fixed-point arithmetic and proportional integral compensators.
