Abstract
In one embodiment, a variable capacitance apparatus is disclosed. The variable capacitance apparatus includes a support structure and a plurality of capacitor units. The support structure has a platform, a plurality of walls extending upward from the platform, and a plurality of channels formed between adjacent ones of the walls. Each of the capacitor units has a capacitor and first and second capacitor leads. The plurality of capacitor units are mounted to the support structure so that the plurality of capacitors are positioned within the plurality of channels. Adjacent ones of the plurality of capacitors are separated from one another by one of the plurality of walls to prevent arcing therebetween.
Claims19
A variable capacitance apparatus comprising:
- a support structure comprising:
- a platform;
- a plurality of walls extending upward from the platform;
- and
- a channel formed between two adjacent ones of the walls;
- and
- a plurality of capacitor units, each of the plurality of capacitor units comprising a capacitor and first and second capacitor leads, the plurality of capacitor units mounted to the support structure so that one of the plurality of capacitors is positioned within the channel, wherein adjacent ones of the plurality of capacitors are separated from one another by one of the plurality of walls to prevent arcing therebetween.
A variable capacitance apparatus comprising:
- a support structure comprising:
- a platform;
- and
- a lower basin beneath the platform, a bottom surface of the platform forming a roof of the lower basin;
- and
- a switching circuit unit comprising a first circuit board and a plurality of switches operably mounted on the first circuit board, the switching circuit unit disposed at least partially within the lower basin;
- a potting material at least partially filling the lower basin and embedding the plurality of switches;
- and
- a plurality of capacitor units mounted to the support structure above the platform, the plurality of capacitor units electrically coupled to the plurality of switches.
A variable reactance apparatus comprising:
- a support structure comprising a platform, a plurality of walls, and at least one slotted wall;
- a variable reactance circuit associated with the support structure;
- a second circuit board comprising a lower edge and a plurality of slots extending upward from the lower edge;
- at least a portion of an operation circuit operably located on the second circuit board;
- and
- the second circuit board mounted to the support structure in an upright manner relative to the platform by:
- (1) slidable mating of the plurality of walls within the plurality of slots of the second circuit board;
- and (2) slidable mating of a lower portion of the second circuit board within a slot of the at least one slotted wall of the support structure;
- and
- the portion of the operation circuit electrically coupled to the variable reactance circuit.
