Abstract :
Power losses of the motor drive depend to a large extent on the switching frequency, currents, and supply voltage of the power inverter. As these three parameters affect the motor torque and speed, they must be considered in the synthesis of the inverter adjustment algorithms. In this paper, a new toolbox for exploring the modulation techniques is described. Some methods of the load-dependent control of motor drive inverters are discussed and examined by simulation and experimentation. The developed control systems improve economic indicators of induction motor drives.
