Abstract
Official abstract text for this publication.
A device including a mechanism detecting a position of a neutral of a power supply source for an electrical energy apparatus, such as a battery charger of an electric or hybrid motor vehicle, and a mechanism connecting a capacitor for limiting leakage currents between the neutral and an electrically conducting structure in which the apparatus is placed. The device can be used to limit leakage current during recharging of an electric or hybrid traction motor vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for limiting leakage currents for an electrical apparatus, the device being connectable, individually, to a three-phase supply network and a single-phase supply network as a source that supplies the electrical apparatus with electrical power, the device comprising: circuitry including: a capacitor element, the capacitor element including a first capacitor and a group of capacitors comprised of second through fourth capacitors, first through…
