The issues of active vs. passive means of power quality improvement in aerospace applications are addressed. The concept of nonlinear loads, i.e., the relationship between the current harmonics and system power factor has been reviewed. both passive and active means of harmonic minimization are discussed, including resonance issues associated with passive networks and presenting an active rectifier switched in a Space Vector (SV) Pulse Width Modulation (PWM) manner. The analysis of power quality in aerospace applications is presented, together with the industry governing standards. Results of case studies are given, using Saber hierarchical tools for the system analysis. Both simulation and experimental results are provided, demonstrating power quality improvements obtained by passive and/or active means in several aerospace applications.
Novica A. Losic (Mí83-SMí94) was born in Zajecar, Yugoslavia, in 1946. He received Dipl.Ing, from Belgrade University, M.Eng, and Ph.D. degrees from the University of Toronto, Toronto ON, Canada in 1970, 1977, and 1981, respectively all in electrical engineering. During the past 37 years, he has been with General Electric Company, University of Wisconsin, Parkside, and Lockheed Martin-KAPL, Schenectady, NY, where he designed and developed signal processing, power electronics, and control circuits as well as teaching and conducting research in the areas of circuit systems and controls He is currently with Honeywell Aerospace, ON Canada. He has published over 60 research papers and has been granted 11 US patents. Dr. Losic is a member of Professional Engineers of Ontario, the New York Academy of Sciences and a senior member of IEEE.
