| description | An excess non-linear and unbalanced load application increases the power quality (PQ) problem by injecting harmonic current. The avoidance of neutral current control creates additional PQ problems due to excess circulating current in modern <i>3</i><inline-formula><math display="inline"><semantics><mi>φ</mi></semantics></math></inline-formula><i>4W</i> applications. Therefore, this manuscript suggests improved <inline-formula><math display="inline"><semantics><mrow><mo> </mo><mi>α</mi><mi>β</mi></mrow></semantics></math></inline-formula> transform-based voltage and current control approaches for both <i>3</i><inline-formula><math display="inline"><semantics><mi>φ</mi></semantics></math></inline-formula><i>3W</i> and <i>3</i><inline-formula><math display="inline"><semantics><mi>φ</mi></semantics></math></inline-formula><i>4W</i> shunt active filter (SAF) applications. In the proposed approach, a novel combined voltage and current (NCVC) control approach is presented for modern <i>3</i><inline-formula><math display="inline"><semantics><mi>φ</mi></semantics></math></inline-formula><i>3W</i> systems by using voltage and closed-loop current controllers.
