| Popis: | Given the cost reduction of power switching devices, 2/3level hybrid inverters have been recently presented with the voltage generation capability close to the sinusoidal voltage. The hybrid inverter, while having the benefits of the conventional three-level inverters, has fewer switching devices, which will reduce the cost, size, and total weight of the inverter. In this paper, a 2/3 hybrid inverter containing eight switches and two diodes is used to control the speed of a three-phase asynchronous motor, which has four switches and two diodes less than the conventional three-level inverter. The indirect rotor‐flux oriented vector control is proposed for speed control, the control loops of the system are designed, and a proper and efficient carrier wave based switching technique is proposed for the hybrid inverter. In order to verify the efficiency of the proposed inverter and its control, a variety of simulations are performed in the MATLAB/Simulink software and the speed control results in motor mode and step changes in load torque are presented. |
