Instantaneous Power Theory and Applications to Power Conditioning

This book presents a deep review of various power theories and shows how the instantaneous active and reactive power theory provides an important basic knowledge for understanding and designing active filters for power conditioning. The only book of its kind, it also demonstrates how the instantaneous active and reactive power theory can be used for combined shunt-series filters and in Flexible AC Transmission Systems (FACTS).
