Unified power quality conditioner (UPQC) with voltage dips and over-voltages compensation capability

open access: yesRE&PQJ
Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. Diverse control techniques have been proposed to evaluate the instantaneous output voltage of the series active power filter of the UPQC but, in most cases, these ...
