ABSTRACT:
A power supply for producing a high voltage DC output. The power supply comprises a primary winding and a series of secondary stages each having secondary windings coupled to the primary winding through a magnetic circuit. Each secondary stage comprises a printed circuit board with the secondary windings formed as a series of independent coils or turns on the board substrate. The magnetic circuit comprises a series of segments which are separated by an insulating film to maintain each segment at the same potential as the associated printed circuit board. Each coil includes a rectifier element for converting the induced AC voltage into a DC voltage. The rectifier elements are connected in series and the printed circuit boards are coupled to produce a high level DC voltage output signal, for example, a minimum 200 kV output. To compensate for Magneto Motive Force (MMF) losses through the insulating film, the rectifier elements include a compensation capacitor.
