Performance analysis of compensation current extraction techniques for 3Ф, 3-wire shunt active power filter under unbalanced supply

Real-time implementation of an amplitude-locked loop: a validation on the dSPACE DS1006-based platform

“…They can also be classified into open-loop techniques and closedloop techniques. A comparative evaluation of some of these methods can be found in [1]. The importance of efficient extraction and the applications thereof are covered extensively in [2].…”
