Abstract
A high voltage high power DC source includes a magnetic flux pole structure responsive to a high frequency, relatively low voltage source inductively coupled to the pole. Multiple AC to DC converters inductively coupled to the pole are connected in series, stacked relationship with each other, to derive the high voltage, high power DC output. Each stage includes a pair of oppositely wound planar coils on opposite sides of a printed circuit board. The printed circuits of the different stages are displaced from each other and a coil driven by the high frequency source.
