Abstract :
The efficiency characteristics of induction machines driven by open-loop varying voltage varying frequency (VVVF) inverters is analyzed numerically in detail. Some design considerations and artificial experiences are obtained. A fuzzy efficiency optimizing control scheme is proposed without the addition of any hardware cost for the inverters. The simulation results show that the efficiency optimizing control proposed in the paper can increase the efficiency of induction machines under the different operation conditions. Furthermore, the experiment results on a 1.1 KW induction machine prototype verify the validity and effectiveness of the theoretical analysis and the design.
