Abstract :
A 25 kW, 15 kV output, 50 kHz transformer with 100 kV primary to secondary isolation is described. The transformer will be the central element of a resonant inverter. Six of these resonant inverter outputs will be connected in series to produce 90 kV for an airborne application. The transformer and high voltage will be in an SF6 atmosphere. Unique ceramic coil forms and insulating shells are used to minimize size
