Abstract
The process and the device enable the electrical powering of a circuit having a conductor (1) with high thermal inertia by means of a transistor (3) with low thermal inertia. According to the invention, the device comprises a current limiter circuit (4,5,7,11), a voltage detector circuit (8) and a control microprocessor (6) which, according to a pre-established program, controls the flowing and stoppage of current in the power transistor (3) controlling the powering of the conductor (1) with high thermal inertia. Application to the control of lights in automobile vehicles.
