1. General principles and different couplings
1.1 First approach
Consider an electrical system consisting of three independent loads Z 1 , Z 2 and Z 3 supplied by three voltage sources e 1 (t), e 2 (t) and e 3 (t) (figure 1 ).
Every single-phase circuit has an "out" conductor and a "return" conductor, essential for completing the circuit.
Such a system has interesting properties in the particular case where :
