| Abstract |
This paper presents two three-phase line-interactive UPS systems with active series-parallel power-line conditioning capability. Synchronous Reference Frame (SRF) based controllers, are used to compensate harmonic currents generated from any configuration of non-linear loads. The performance of the UPS systems is evaluated in three-phase, three-wire and four-wire systems, which allow an effective power factor correction, load harmonic current suppression, output voltage regulation and harmonic suppression of the input voltages, for balanced and unbalanced non-linear loads. Simulation results to verify the good performance of the proposed line-interactive UPS systems are shown. |
