Abstract
Presented is a system and method for providing electrical isolation in vehicle power systems. The method comprises placing linear optimized isolation transformers in structures of a vehicle at positions that minimize the propagation of energy spikes into internal electronic systems, for example in the wing root of an aircraft where electrical cables from a generator associated with an engine enter the fuselage. The system includes a linear optimized isolation transformer with a core that has primary side winding isolated from a secondary side winding by an isolation dielectric. The isolation dielectric maintains a high value isolation independent of pressure differences due to operation at different altitudes. In embodiments, linear optimized isolation transformers for each phase of a power distribution system couple power from a generator through a structure of a vehicle thereby increasing electrical isolation of electrical components inside the structure from electrical surges originating outside the structure.
