Source of power supply

Definition

One calls source of Power supply any device which can provide or evacuate electrical energy. This electricity can have the form of a alternate Signal , like continuous, multipolar, multitensions, signal Triangulaire, Créneau, nelle Impulsion… or even " fantaisiste" (Harmonic S complexes).

Two big families emerge:

the Source of tension, ideally, gives a tension independent of the running output. Characterized by the amplitude of the Potential difference to vacuum (U for I = 0 Amp S), the Résistance interns (often neglected R ~=0 Ohm S), the current of courcircuit ( Icc for U = 0 Volt, the latter is not always supported by the source, in this case the maximum current Imax ), for the stabilized sources of laboratory or the special cases of internal design of the curves of characteristics of behavior are given by the manufacturer.
the Power source, ideally, gives a current independent of the delivered tension. Characterized by the amplitude of the current output in short-circuit (I for U = 0 Volts), internal resistance (often neglected R ~ infinite Ohms), the tension with the opening ( Uo for I = 0A, the latter is not always supported by the source, in this case the maximum tension Umax).
