Abstract :
The possibility is studied of UPS (uninterruptible power supply) control based on the voltage vector referred to a rotating reference frame with velocity corresponding to voltage pulsation and on voltage pulsation itself. To verify the feasibility of the control strategy, a digital SPICE-aided simulation is reported. The numerical results show that, with an asymmetrical load, a pulsation ripple is present owing to the nonsinusoidal voltage waveforms. Nevertheless, the computer harmonic distortion values are acceptable
