1. Introduction Three-phase unbalance is a prevalent power quality issue in low-voltage distribution systems, mainly caused by dispersed single-phase loads, charging piles and residential electricity consumption. Two mainstream solutions are widely used in the industry: mechanical relay phase-switching balancers and IGBT-based active compensation devices (SVG/APF/Active Load Balancer). This articl...
