Abstract: A solid-state magnet controller powered by an AC generator using separate silicon controlled rectifier (SCR) bridges to drive current through the magnet in opposite directions. The invention eliminates high voltage transients, first by switching flyback diodes across the magnet using solid state devices, then employing secondary discharge methods to dissipate the remaining stored magnetic energy. Isolated DC-to-DC converters are used as a means of providing drive signals to the solid-state elements. A method to prevent inadvertent FET turn-on is included, as well as a method to slowly decrease the magnet current when desired.

Abstract: A solid electrolytic capacitor that is capable of exhibiting stable electrical properties (e.g., leakage current and ESR) in a wide variety of operational conditions is provided. The capacitor contains an oxidized anode body and a conductive polymer coating overlying the anode body. The conductive polymer coating contains multiple layers formed from a dispersion of pre-polymerized conductive polymer particles. Unlike conventional attempts, the present inventors have surprisingly discovered that capacitors formed from such conductive polymer dispersions can operate at high voltages, and also achieve good electrical performance at relatively high humidity and/or temperature levels. More particularly, the present inventors have discovered that the problem of layer delamination may be overcome by carefully controlling the configuration of the conductive polymer coating and the manner in which it is formed. Namely, the coating contains a first layer that only partially covers the anode body.
