Loss Minimization Technique in Scalar-Controlled Induction Motors

摘要

Core losses are a menace to 3-Phase Induction Motors (3PHIM) and can only be taken care of by adjusting their voltage/frequency ratios using an efficient Voltage Source Inverter (VSI) like the MCT-Inverter. Scalar-controlled induction motors have their speeds controlled by controlling their stator voltages and frequencies in such a way that the ratio of the stator voltage to the frequency is always kept constant. The drive technology of most scalar-controlled 3-phase induction motors utilizes Voltage Source Inverters such as IGBT-Inverter to achieve variable voltage variable frequency.......
