Abstract
A compensation system for compensating for a leakage current of an electric battery charger on board a vehicle and connected to a power supply network by an electrical ground, by a neutral phase and by at least one phase other than the neutral phase, a residual current differential protection device being interposed between the battery charger and the power supply network, a leakage current flowing from the battery charger to the power supply network on the electrical ground. The compensation system includes a compensation mechanism for compensating for a leakage current and configured to emit, on the electrical ground, a compensation current of same amplitude as the leakage current and of a phase that is the opposite of phase of the leakage current.

11. A compensation system for compensating for a leakage current of an electric battery charger within a powertrain on board a vehicle and connected to a power supply network by an electrical ground, by a neutral phase and by at least one phase other than the neutral phase, a residual current differential protection device being interposed between the battery charger and the power supply network, the system comprising:
a compensation means for compensating for a leakage current flowing from the battery charger to the power supply network on the electrical ground, the compensation means configured to emit, on the electrical ground, a compensation current of same amplitude as the leakage current and of a phase that is the opposite of phase of the leakage current. - View Dependent Claims (12, 13, 14, 15, 16)
