Abstract
A circuit and method for converting three-phase .DELTA. AC to a higher voltage DC output. The method utilizes first, second and third rectifying circuits and a storage circuit to provide DC. The circuit herein does not require an independent DC power source, nor a neutral AC connection, as used for conventional Y connected power systems. The circuit herein also provides a uniform loading to all three phases of the AC input. A preferred embodiment is provided herein comprised of twelve diodes and three capacitors, wherein the diodes rectify the current, and the capacitors store charge.
