RESUMO

Programmable AC Power Source with Low Harmonic Distortion used to analyse equipment performance when the quality of power supply deviates from the ideal standards is, nowadays, quite imperative. In addition to other applications, this allows for the derivation of distinct load sensitivity and supportability limits as far as power quality is concerned. This work presents a Novel Topology of Class D Power Amplifier used in the power stage of the programmable AC Power Source with low harmonic distortion used to analyse electronic equipment performance. The power stage needs a programmable three phase reference signal to form a Programmable AC Power Source so a project and a laboratory prototype of a programable three phase function generator is also presented.
