Electric current amperage measuring method for actuator of bus system, involves injecting sequence of stimulating pulses into resonant circuit, where duration of pulse is shorter than duration of pulse interval to subsequent pulse

摘要

The method involves conducting the electric current (I) through a conducting part (1) in such a manner that the magnetic field generated by the current influences the inductance of an inductive unit (3) in a resonant circuit (C2). A sequence of stimulating pulses is injected into the resonant circuit, where the duration of a stimulating pulse is shorter than the duration of the pulse interval to the subsequent stimulating pulse, and an absorbed oscillation in the resonant circuit is produced by each stimulating pulse.
