Abstract

See full text

The electronic device includes a battery, an electrical energy generator and, between the generator and the battery, an inductive voltage boost converter. The device further includes a circuit for measuring the voltage supplied by the generator which is formed by: a measuring capacitor arranged in parallel with the battery and having a measuring terminal connected to a voltage measuring circuit, a diode located between the inductor output terminal and the measuring terminal, a switch arranged between the measuring terminal and the earth terminal. A control unit is arranged to periodically activate a mode for measuring a voltage at the measuring terminal. The measuring capacitor is selected such that the measuring voltage is much higher than the generator voltage and lower than the battery voltage at a minimum generator voltage allowing charging of the battery.
