Title:
CANCELLATION OF PARASITIC INDUCTANCE IN FILTER CAPACITORS CONNECTED IN PARALLEL TO ELECTRIC CONVERTERS IN AN ELECTRICAL SYSTEM OF A VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/143384
Kind Code:
A3
Abstract:
The invention relates to a filter circuit for reducing electrical interference emissions in an electrical system (2) of a motor vehicle, comprising: a first inductance (16) in a serial branch; a capacity (10) in a parallel branch, whereby the first inductance (16) and the capacity (10) are interconnected by means of a node; a second inductance (18) in the serial branch which is connected to the first inductance (16) and the capacity (10) by the nodes, the first inductance (16) being magnetically coupled to the second inductance (18) such that a parasitic inductance (12) is reduced in the parallel branch.
