Abstract
A voltage limiter device of an assembly of photovoltaic modules, including: (a) means (Z1) forming an electronic switch for a current of said assembly; (b) comparison means (Comp, R1, R2, C2) for comparing a voltage at the output of the limiter with a reference voltage value (Vref); and (c) means for controlling the means forming an electronic switch, depending on the result of the comparison carried out by the comparison means.
Claims27
A voltage limiter device of an assembly of photovoltaic modules, including:
- an electronic switch for a current of said assembly, in order to interrupt a current delivered by said assembly of modules,
- a first comparator to compare a voltage at the output of the limiter with a reference voltage value,
- a controller of said electronic switch, in order to open or close said switch, depending on the result of the comparison carried out by the comparator means.
A voltage limiter device of an assembly of photovoltaic modules, including:
