Özet

The stator current and electromagnetic torque transients of induction motor have been investigated in this paper, when the motor is transferred to uninterruptible power supply (UPS). The motor is directly fed by the infinite bus before the power outage, then it is transferred to the UPS system, which consists of two cascaded 3-phase pulse width modulated converters. Both converters are controlled by a single fixed-point digital signal processor (DSP). The computer simulation results of the UPS and motor are obtained from Matlab Simulink models and these results are compared to the experimental ones.
