  • Control circuitry of a microcontroller of a photovoltaic system without battery and associated method and devices
    Patent number: 12484337
    Abstract: A control circuit of a controller of a photovoltaic system is provided, the control circuit including an input, an output, a start unit consisting of a power dissipation circuit, a voltage regulation circuit and a comparator, a first switch having a position wherein the start unit is connected to the input and an inverse position, and a second switch having a position wherein the input and the output are not connected and an inverse position. The comparator compares the voltages of the dissipation circuit and of the regulation circuit, the comparator outputting a command voltage of the two switches on the basis of the comparison.
    Type: Grant

  • Circuit for charging an electric battery by means of a photovoltaic module
    Patent number: 10715032
    Abstract: The invention concerns a circuit for charging a battery by means of a photovoltaic module, including: input and output terminals intended to be respectively coupled to the module and to the battery; a converter including input and output terminals respectively coupled to the input and output terminals of the charging circuit; a control circuit including power supply terminals coupled to the output terminals of the charging circuit; a switch coupling one of the output terminals of the converter to one of the output terminals of the charging circuit; and a detection circuit configured, when the voltage between output terminals of the charging circuit exceeds a threshold, to send an order to turn off the switch and stop the converter for a predetermined period.
