The speed and the power factor are controlled in order to optimize the operation of an adjustable speed slip power recovery drive. This is accomplished by means of a variable voltage - variable frequency - variable phase angle power converter. The function of the digital controller of the power converter is to provide the on line speed and power factor regulation. The appropriate built hardware and the software developed are described. This scheme has an accurate voltage output with very low harmonic content, a good resolution for the phase angle regulation and the frequency control with the possibility of range extension. (EN)
