"Among the book's strengths is that it includes modelling and control methods for different ac-dc converter topologies used in the active improvement of power quality. It also facilitates understanding using real parameters for simulations in MATLAB and PSIM programs as well as experimental tests to show the efficiency of grid current harmonics reduction according to valid standards.""I recommend this book as a useful text for students and scholars who work in the area of power quality improvement and are interested in design and modelling"--Marian P.
