A device determines a corrected setting of a neutral current at an output of a rectifier stage of an electrical or hybrid automotive vehicle battery charger without galvanic isolation. The device includes a phase-locked loop to determine an instantaneous frequency of the network as a function of a measurement of a voltage of an electrical supply network, a regulating mapping to determine a neutral current setting as a function of a setting of battery current, a device to calculate an amplitude of a frequency variation of the network as a function of the instantaneous frequency, a correction mapping that receives as input a value of the amplitude of the frequency variation and emits as output a correction value of the neutral current setting, and a summer to determine a corrected neutral current setting by adding the correction value of the neutral current setting to the neutral current setting.
