| Abstract |
The object of this paper is to present some control strategies of two and three phases three-level voltage inverters and their application in the drive of the single phase induction motor without capacitor and three phases one. We present in the first time a global model of three-level voltage inverters using Petri nets. Then we expose five control strategies of these converters. Some of these strategies are novel and are presented for the first time. The common points of these different strategies are feeble harmonics rate of the output voltage current and then the torque of the machine. In the last part of this paper, we present the performances of a direct field oriented control of a three phases induction motor fed by two synchronous PWM rectifters- three phases three-level voltage inverter. This drive system find applications in great power and high speed drive fields as the electrical traction. |
