Photovoltaic device with electronic switch(es)

摘要

Photovoltaic device comprising a photovoltaic generator comprising a number of photovoltaic cells, characterized in that it comprises at least one switch with a control device comprising a control capacitor (Ccde) and a control resistor (Rcde), linked to the switch so as to slow down the control of the opening of the switch, to allow at least one cell of the photovoltaic generator to switch from a short-circuit operating mode to an open-circuit mode, or vice versa.

1. Photovoltaic device comprising
a photovoltaic generator comprising a number of photovoltaic cells, wherein the photovoltaic generator comprises a first switch (T1) disposed in parallel on a branch between two terminals of at least one cell of the photovoltaic generator, and a control device linked to the first switch comprising a control capacitor (Ccde) and a control resistor (Rcde) so as to slow down the control of the opening of the first switch, to allow at least one cell of the photovoltaic generator to switch from a short-circuit operating mode to an open-circuit operating mode, or vice versa; at least one control switch that is an MOS transistor, comprising a gate capacitor (Cg) and a gate resistor (Rg) in series, the control capacitor (Ccde) and the control resistor (Rcde) being arranged in parallel at the input terminal of the assembly formed by the gate resistor (Rg) and the gate capacitor (Cg), wherein the control device also comprises a diode (Dcde), arranged to prevent discharge of the gate capacitor (Cg) to a voltage generator (Vcde) which would be arranged at the terminals of the assembly formed by the control capacitor (Ccde) and the control resistor (Rcde) to transmit a voltage command to the control switch.
