<p>A voltage adjustment device, particularly for recharging service batteries, characterized in that it is constituted by a battery power supply circuit, comprising switching means, which are connected by way of a first terminal to first filtering means which receive in input a voltage signal and a current signal, and voltage calibration means, which are connected in input to a second terminal of the switching means and in output to the battery, the calibration means being adapted to provide a threshold voltage suitable for recharging the batteries; and by a control circuit comprising a comparator which receives in input a first signal, responsive to a reference voltage, and a second signal, responsive to the threshold voltage, the comparator being adapted to compare the first and second signals and to send an enabling error signal to means for setting the on/off switching threshold of the switching means in order to allow the calibration means to ensure that the threshold voltage is substantially constant. <IMAGE></p> |
