<p>The invention realizes a device for the adjustment of the terminal voltage of a single-phase alternator (1) coupled to an endothermic motor, said device including a current sensor (10) of the alternator load transferring a signal (Is) to the entry of a comparator logic circuit (21), said comparator circuit emitting a first outgoing signal (25) suitable for controlling a shutter (23) connected to the accelerator of the endothermic motor. Said comparator circuit (21), in case of a substantial loss lack and of reduced revolutions per minute, emits a second electric signal (26) suitable to close a switch (22) connecting at least an auxiliary capacitor (17) to the excitation circuit (18) of the alternator (1), so that the excitation current causes a voltage to the alternator terminals substantially not lesser than 50% of the rated voltage. <IMAGE></p> |
