This paper presents negative impacts of capacitive loads (with very low ZL) on the shunt active power filter accuracy. First, an advanced universal power quality conditioning system (A-UPQS) is proposed for three-phase four-wire systems under non-ideal waveforms. Considering the suggested compensation algorithm, the advanced UPQS is able to suppress source-end current harmonics caused due to the distorted-unbalanced load-terminal voltages. Moreover, an independent single-phase converter is suggested at the load-end in order to regulate the DC-link voltage. Unlike a previous proposition of a three-phase converter at the source-end, the new suggestion will be able to regulate the DC-link without any distortion. Therefore, the source-end three-phase currents would be purely sinusoidal. Simulations show that the proposed advanced UPQS performs effectively in line with the desirable outcomes.
