Abstract (en)

[origin: EP1209709A1] The equipment state transmission system has a battery (3) and an electrically isolated connection (7) between the electrical circuit and an output (S). A variable voltage (1) adjusts the current in the switch (5) as a function of the voltage generator voltage. There is a self inductive filter (6) in series with the switch and a capacitor (13) which stores and releases part of the energy following the variable voltage generator.
