Active vs. Passive Means of Power Quality Improvement in Aerospace Applications 2002-01-3226

The issues of active vs. passive means of power quality improvement in aerospace applications are addressed. The concept of nonlinear load, 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 in several aerospace applications.
