Abstract
This invention relates to a synchronous generator comprising a stator having output winding means connected to a load or loads and main voltage building up means including capacitor means and capacitor exciting winding means, said capacitor means being connected across said capacitor exciting winding means, said output winding means and said capacitor exciting winding means being provided on a common core; and a rotor having field winding means across which a rectifier means is connected; wherein said synchronous generator further comprises auxiliary voltage building up means provided in said stator, said auxiliary voltage building up means causing the output winding means to provide said stator with armature reaction when initial large current has flowed through said auxiliary voltage building up means from said output winding means to thereby build up output voltage across said output winding means with the start of said generator. The auxiliary voltage building up means may be provided either in a circuit including the output winding means or in a circuit including an auxiliary winding wound on a core for the output winding means.
