This paper describes the experiment results with noise reduction in induction motor drive fed by the voltage inverter. The tests were conducted using the hybrid PWM method proposed in [1]. The HPWM reduces computational overhead in space vector computation and introduces k0 factor. The proper shaping of k0 allows either reducing switching losses in power devices or minimizing current ripple in the...
Induction motors are the workhorse of our industries, continuously applied in new areas with improved performance utilizing modern power electronics and digital controls. This paper proposes a new computationally efficient real-time control for induction motor drives using state-of-the-art digital signal processing (DSP) technology, but without using a speed sensor. This control is named advanced...
This paper presents the thermal behavior of a three-phase induction motor under direct torque control, when supplied by a three-phase voltage source inverter with fault tolerant capabilities. For this purpose, a fault tolerant operating strategy based on the connection of the faulty inverter leg to the dc link middle point was considered. The motor thermal profile is obtained through the use of nine...
