摘要：A new approach for a fixed switching frequency direct torque control (DTC) of an open end winding induction motor configuration using four level inverter is proposed. The four level SVPWM voltages are generated by using two conventional two level inverters which are fed with the unequal dc link voltages at a ratio of 2:1. A decoupled algorithm for the two inverters feeding the open end winding induction motor is proposed. However, the proposed DTC scheme does not require the sector information of the estimated fundamental stator voltage vector and its relative position with respect to the stator flux vector. With the proposed method simulation clearly demonstrate simple numerical calculations and results in a better dynamic manner
