In this paper the factors influencing the self-excitation process in the synchronous generator and a method of this process improvement are described. In the case of high stator windings inductance commutation process in the rectifier at the generator output interfere with successful self-excitation, which is confirmed by analytical calculations and practical experiment. Use of the excitation current pulse regulator with the input capacitor allows not only to control current according to the generator rotation speed and load, but also to provide initial magnetization of the excitation winding, that in turn compensates influence of the commutation processes. The generator self-excitation at low speed is provided selecting the initial voltage level of the regulator input capacitor.
