There is provided an apparatus for pulse charging of a load capacitor, the apparatus comprising: a ferrous cored transformer having a primary winding and a secondary winding; a primary circuit connected to the primary winding; a secondary circuit connected to the secondary winding, the secondary circuit comprising the load capacitor; and an uncoupled inductance in the primary circuit or the secondary circuit, the uncoupled inductance reducing the coupling coefficient between the primary circuit and the secondary circuit.

Pulse charging of a capacitor

A material for 3D printing is described. The material comprises a polymeric composition comprising a thermoplastic polymer; and from 50 to 99 wt. % ceramic particles comprising a metal, wherein at least 50% by weight of the particles have a diameter in a range from 10 to 100 &#x3bc;m; wherein the material has a dielectric strength of at least 5 kV/mm and/or a dielectric constant of at least 5.

Material for 3D printing and a 3D printed device

A radio frequency (RF) transmitter, comprising a Tesla transformer and an LC oscillator, said Tesla transformer comprising inner and outer conductors (), said inner conductor () comprising a generally tubular magnetic core () carrying a conductive member () on its outer surface and said outer conductor () comprising a generally tubular magnetic core () carrying a conductive member () on its inner surface, said LC oscillator including a secondary winding module () comprising a generally tubular body () carrying a conductive coil () on its outer surface, said inner conductor (), outer conductor () and secondary winding module () being arranged in a substantially concentric nested configuration such that said inner conductor () is located within said secondary winding module () and said secondary winding module () is located within said outer conductor (), wherein a first portion () of relatively high permittivity dielectric material is provided between said conductive member () of said inner conductor () and said conductive coil () and a second portion () of relatively high permittivity dielectric material is provided between said conductive coil () and said conductive member () of said outer conductor ().

RF transmitter and method of manufacture thereof

This invention relates to a method of potting a component, namely encasing a component () in a potting compound () with, optionally, all or some of the voids in the component also being filled with potting compound. In particular, the present invention relates to potting a component that will be subject to high electric field strengths in use. The method comprises introducing an inert gas into a first pressure vessel () containing the component to be potted thereby to create an inert environment, introducing a potting compound into the first pressure vessel and allowing the potting compound to cure in the inert environment.
