The design of shunt active power filters (APF) and hybrid active power filters (HAPFs) characterized by better performance, high reliability, low cost and failure rates will be the major trend in the future. Over the past few decades, significant researches were focused on addressing the technical challenges associated with the parameter design, operation and control of the APF and different HAPFs. However, the comprehensive review of their V-I characteristics, cost, reliability, power loss and tracking performance has been rarely studied. Therefore, this chapter aims to provide a clear picture of the selection of APF and different HAPFs based on V-I characteristic, cost, reliability, power loss and tracking performance. The supreme one will be selected among APF and different HAPFs by considering the V-I characteristics, cost, reliability, power loss, and tracking performance. Finally, the experimental results of APF and different HAPFs will be provided to verify their compensation performances.
