Modeling of Power Electronic Circuits and Control for Airborne Electrical System Analysis 2004-01-3191

This paper gives an overview of advanced power electronic circuits and control modeling techniques for power quality and dynamic stability study of airborne electrical systems. A unified modeling framework based on averaging is presented, and its applications to PWM as well as resonant and soft-switching converters are discussed in detail. Discontinuous conduction mode, peak-current control, variable-frequency PWM, and ac-dc converters with active power factor correction are among the specific topics discussed. Feasibility of automatic model generation by means of a symbolic analysis program package is also demonstrated. Compatibility among models of converters operated at significantly different switching frequencies is identified as a key issue for average-based analysis of large power electronic systems that requires future study.
