Abstract:
A method reduces noise resulting from a current surge in a circuit. A plurality of loading elements, parallel with the circuit being protected, are connected sequentially and disconnected. The connection of the loading elements results in a ramping up of current through the circuit without a sudden surge. In a preferred embodiment, an apparatus for slowing a current change in a circuit is described. The apparatus comprises a plurality of loading elements placed in parallel with the circuit, each of the elements providing a path for current flow, and a control circuit for selectively opening or closing at least one of said paths to prevent or enable current flow through the at least one of the paths.
