Abstract: A downhole tool may include a high-voltage power supply disposed within a housing to transform input power to the downhole tool from a first voltage to a second voltage greater than the first voltage. The high-voltage power supply may include an array of capacitors, which may include multiple rows of capacitors. The rows of capacitors may be parallel with a symmetric cross section as viewed from an end of the array of capacitors. The high-voltage power supply may also include diodes electrically coupled to the array of capacitors.
