PROTECTION DEVICE AGAINST INTERFERENCE GENERATED BY CONNECTION TO A CONTINUOUS POWER SUPPLY SOURCE OR DISCONNECTION OF THIS SOURCE FROM AN ELECTRONIC ASSEMBLY, TO THE SUPPLY DELIVERED BY THIS SOURCE.

摘要

P This device for protection against disturbances generated by the connection to a source of continuous electrical power or the disconnection of this source from an electronic assembly, on the electrical power supplied by this source, comprises at least one element ( T1) of variable impedance, and means (R1, C1, D1) for controlling this impedance, so that it has a very large first value when said electronic assembly is in the disconnected state, a very second value low when this set is in the connected state, and a value varying slowly from the first to the second value when passing from the disconnected state to the connected state, and rapidly varying from the second to the first value when passing from l state connected to the disconnected state, the current obtained at the output of this element supplying said electronic assembly. /P
