Abstract
Abstract A cascade transformer configuration for generating high DC voltages wherein a preferred embodiment uses nonmagnetic core transformer units, the secondary coils of which are capacitively coupled to the primary coils of adjacent units. The capacitance values are selected so as to provide resonance conditions so that rectifier-multiplier chains connected to each pair of capacitively coupled coils produce DC voltages with the least loss of power. Each pair of capacitively coupled coils can be formed as an integral deck unit and such deck units stacked in a column with their rectified voltages connected in series to produce a high DC voltage output having a uniform DC voltage gradient along the column.
