Abstract
Abstract Power capacitor with minimal self-inductance includes a stack of metal layers mutually superimposed perpendicularly to a given axis, with respective layers of insulation disposed between mutually adjacent metal layers of the stack, the metal layers and the insulation layers being formed with mutually aligned cut-outs in vicinity of the given axis so as to form a free space within the stack, respective surface portions of alternating layers of the metal layers projecting into the free space above one another as electrodes of given common polarity, the surface portions of the metal layers of respective opposite common polarity being disposed symmetrically with respect to the given axis in the free space.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
Power capacitor with minimal self-inductance comprising a stack of metal layers mutually superimposed perpendicularly to a given axis, with respective layers of insulation disposed between mutually adjacent metal layers of said stack, said metal layers and said insulation layers being formed laterally with mutually aligned cut-outs in vicinity of said given axis, said mutually aligned cut-outs collectively forming a free channel within said stack open at opposite ends and along a side thereof, respective surface portions of alternating layers of said metal layers projecting into said channel above one another as electrodes of given common polarity, the surface portions of the metal layers of respective opposite common polarity being disposed opposite one another and symmetrically with respect to said given axis in said channel.
Claim 2
Dependent Claim
124 words
Power capacitor with minimal self-inductance comprising a stack of metal layers mutually superimposed perpendicularly to a given axis, with respective layers of insulation disposed between mutually adjacent metal layers of said stack, said metal layers and said insulation layers being formed laterally with mutually aligned cut-outs in vicinity of said given axis, said mutually aligned cut-outs collectively forming a free channel within said stack open at opposite ends and along a side thereof, respective surface portions of alternating layers of said metal layers projecting into said channel above one another as electrodes of given common polarity, the surface portions of the metal layers of respective opposite common polarity being disposed opposite one another and symmetrically with respect to said given axis in said channel.
Claim 3
Dependent Claim
36 words
Power capacitor according to claim 1 wherein the surface portions of the metal layers of given common polarity are disposed opposite to and spaced from the surface portions of the metal layers of opposite common polarity.
Claim 4
Dependent Claim
44 words
Power capacitor according to claim 1 including electrically conducting bridge means for connecting the surface portions of the metal layers of given common polarity to one another and for connecting the surface portions of the metal layers of opposite common polarity to one another.
Claim 5
Dependent Claim
32 words
Power capacitor according to claim 1 wherein said free space is of a dimension for accommodating therein a load for consuming capacitor energy, said load being electrically connectible to said surface portions.
Claim 6
Dependent Claim
32 words
Power capacitor according to claim 3 wherein said free space is of a dimension for accommodating therein a load for consuming capacitor energy, said load being electrically connectible to said bridge means.
