摘要

Speed control of conventional low-voltage low-power induction motors (LV-LP-IMs) by two-level voltage source inverter (2LVSI) has some difficulties due to limitations of LV-LP-IMs especially insulation system. Besides, the use of multilevel inverters is not cost-effective either. In this paper, the new topology of reduced-switch-count three-level inverter with only eight switches is proposed for speed controlling of LV-LP IM. Eight-switch inverter is a newly three-level converter, which has the fewer number of switching devices, lower cost, smaller volume compared with the conventional three-level inverters, while it has sufficient switching vectors to speed control of IMs. In this paper, the structure and switching vectors of the eight-switch inverter are analyzed, and the direct torque control method based on the switching table and voltage balancing of the DC input voltage are presented for the LV-LP-IM speed control. Simulation results, considering different work conditions, are presented in order to validate finally the good performance of the proposed method. Moreover, the obtained results are compared with 2LVSI and conventional three-level inverters in different aspects.
