Abstract
Abstract An internal grounding arrangement which minimizes output of current spikesy isolating the switching spikes from the input and output includes an arrangement of separate grounding planes for different functional groups of components, such as high current switching, low current switching and input/output components, with RF chokes and a single conductor line. The RF chokes and single conductor provide electrical isolation between the grounding planes of these different functional groups of components.

Claim 1
Independent Claim
170 words
An internal grounding arrangement for a switching DC/DC converter section of a power converter unit having at least one input/output component, at least one high current switching component, and at least one low current switching component, said internal grounding arrangement comprising: a first ground plane for connection to an input-output component; a second ground plane separate from said first ground plane for connection to a high current switching component; a third plane separate from said first and second ground planes for connection to a low current switching component; first means including a plurality of RF chokes interconnecting said first and second ground planes to permit transmission of DC energy but prevent transmission of RF energy therebetween; and second means including a single conductor wire interconnecting said second and third ground planes at a single point of contact therebetween to permit operation of a low current switching component, upon connection to said second ground plane, with minimum interaction with a high current switching component, upon connection to said third ground plane.
