A multiplier assembly for a power supply and a method of manufacturing the multiplier assembly. The multiplier assembly may be a stack of capacitors and support elements electrically and mechanically coupled together to form a first capacitor string and a second capacitor string. The support elements may electrically and mechanically connect adjacent series capacitors in the first capacitor string. Additionally or alternatively, the support elements may electrically and mechanically connect adjacent series capacitors in the second capacitor string. In one embodiment, the power supply may include drive and feedback circuitry capable of controlling operation of the multiplier assembly.
