This paper presents the phase variable model of brushless exciter employed by aircraft integrated starter/generators. The model uses current-flux linkage functions obtained by finite element analysis. Since the developed model contains the exciter machine and its connected rotating rectifier, a particular attention is paid to adequately considering coupling effects between the exciter and the rotating rectifier which govern operation of the rectifier. One important parameter of this coupling is the inductance which contributes in commutation process of the rectifier (commutation inductance). In this regard, a simple finite element analysis technique is proposed to identify the commutation inductance. Finally, the developed model is validated by comparing its results with finite element analysis.
