Title: METHOD AND DEVICE FOR SINGLE-PHASE CONTROL OF AN ON-BOARD CHARGER OF ELECTRIC OR HYBRID VEHICLES WITHOUT GALVANIC ISOLATION
Abstract:
The invention relates to a method for controlling a three-phase charger without galvanic isolation, installed on-board an electric or hybrid motor vehicle, configured to perform a domestic single-phase charge, the charger including a rectifier connected to an electric power supply network via an electromagnetic compatibility filter and to a voltage step-up stage via a smoothing inductor, the voltage step-up stage being connected to a battery, the electromagnetic compatibility filter including a capacitor connected between two supply phases of the charger, the rectifier and the voltage step-up stage each including at least one controlled switch. The method includes the following steps: correcting the displacement factor and the distortion factor of the charger by determining a set value of the absolute value of the input current of the rectifier on the basis of a measurement of the current of the electric power supply network and a measurement of the voltage across the terminals of the capacitor of the electromagnetic compatibility filter, and adjusting the current flowing through the smoothing inductor by controlling the voltage step-up stage and the rectifier on the basis of a measurement of the current in the smoothing inductor, a measurement of the input current of the rectifier and the set value of the absolute value of the input current of the rectifier.
