System and method for reducing partial discharge in high voltage planar transformers

摘要

A device includes a printed circuit board (PCB). The device may also include a high voltage coil disposed on the PCB and a low voltage coil disposed on the PCB. Further, a conductive shield forms a three-dimensional enclosure around the high voltage coil and confines an electric field generated by the device to the PCB.
