Abstract
The voltage surge protection device comprises at least one input designed to be connected to an electric power supply system, at least one output designed to be connected to an electric circuit to be protected, and voltage surge limiting means connected between the inputs and outputs to protect said electric circuit against voltage surges able to be applied on the inputs. The voltage surge limiting means comprise bidirectional series electronic limiting means comprising at least two inputs/outputs connected in series with at least one of said inputs, and which are turned on when a low voltage drop occurs when a circulating current is lower than a current limiting value, and limiting said circulating current by increasing a voltage drop between said inputs/outputs.
