Description


[0001] The invention relates to a buffer capacitor.


[0002] Capacitors are used to store electric charge and in doing so concentrates the charge at the ends of the positive plate and at the point of contact between the capacitor connector and the positive plate. These concentrated charges eventually build up and leak to the negative plate causing resistive heating and inducing inductance impairing the performance of the capacitor and can result in capacitor failure.


[0003] This invention relates to a buffer capacitor having at least one pair of positive and negative plates. Each plate is in the form of a loop current or charge buffer, which comprises an electric conducting material, which may be rigid or flexible, arranged in parallel, electrically insulated from each other by a dielectric material and electrically joined to form a closed continuous electrical loop thereby eliminating the ends of the plates and subsequently charge concentration. The plates are arranged one on top the other in parallel and is electrically insulated from each other by alternate layers of a dielectric material or placed one inside the other and is electrically insulated from each other by a dielectric material and can be tightly wound or laid flat. Each plate is provided with a conventional or a buffer connector, which comprises of a length of an electric conducting material which may be thin in cross-section over part or all of its length and electrically insulated over part of its thin length, the remaining length being of suitably sized and shaped cross-section, or either or each end provided with an eyelet for electrical connection. The thin cross-sectioned un-insulated part of the connector is electrically connected to the plate and the remaining length is folded back parallel and is insulated from the connected length or folded around the plate with the un-insulated length electrically connected to the plate and the remaining length insulated from the plate and the eyelet ends are electrically connected in each case to form a closed continuous electrical loop thereby reducing or eliminating charge concentration at the point of contact between the plate and the connector. Or each positive and negative plate is comprised of a rigid or flexible electric conducting material formed into a current or charge buffers by providing each end of each plate with a conventional or buffer connector, or each end of each plate is provided with or formed into a current or charge buffer with a conventional or buffer connector electrically connected to each current or charge buffer. In each case at least one positive and one negative plate is arranged in parallel one on top of the other and is electrically insulated from each other by alternate layers of a dielectric material and the conventional or buffer connectors at the ends of the same plate is electrically connected after tightly winding or remaining rigid and is electrically connected in each case forming a closed continuous electrical loop and can be used for electrical connection.
