Abstract
Abstract Device for regulating the voltage of an electric energy source constituted of a group of solar cells gathered into modules. Each module have one terminal connected to a common conductor and an other terminal connected through a diode to a distribution conductor. The device comprises electronic interrupters connected between the common conductor and the terminal of a module connected to the diode, so as to short-circuit the module. A proportional shunt is connected between a point at the distribution conductor potential and the common conductor. A differential amplifier is provided between the distribution conductor and a reference voltage generating device. An analogdigital converter the input of which is connected to the output of the differential amplifier and a part of the outputs of which control the electronic interrupters, the remaining outputs controlling the proportional shunt.
