Abstract
This device comprises, at a first end (1) of the line, at least one controlled voltage source (SV2) and a current receiver (RI2) capable of detecting the current (I) flowing in the line (L) and, at the second end (3) of the line, at least one controlled current source (SI2) and a voltage receiver (RV2) capable of detecting the voltage (V) present on the line, the controlled current source (SI2) being adapted to impose the flowing in the line (L) of a programmable current (I) that is independent of the voltage receiver (RV2), of the voltage source SV2) and of the current receiver (RI2), while the controlled voltage source (SV2) is adapted to impose on the line (L) a programmable voltage (V) that is independent of the current source (SI2), of the current receiver (RI2) and of the voltage receiver (RV2). Application to electronic ignition systems for internal combustion engines.
