CONTROL METHOD FOR A CHARGER DEVICE INTENDED FOR AN ELECTRIC VEHICLE

Abstract

A method for controlling an electrical system for a grid-type vehicle is activated, the system comprising: a bidirectional DC power source; an electrical machine comprising a rotor, a stator, a first winding and a second winding, in which the stator includes the first winding; a first control circuit connected to the first winding and comprising an input configured to be coupled to the grid; and a second control circuit through which the second winding is connected to the bidirectional DC power source.The method consists of coupling the first control circuit to the grid; operating the first control circuit according to a current process spatial vector field orientation so as to convert the supplied grid electrical energy into an alternating voltage waveform, which periodically includes the switching of a current vector in a dq reference frame between diametrically opposite first and second vector points, the current vector being disposed at a certain angle with respect to the d-axis to determine a d-axis component value and a q-axis component value; and loading the bidirectional DC energy source using an alternating voltage waveform induced in the second winding resulting from magnetic coupling between the first and second windings.
