An Investigation into the Next Generation of High Density, Ultra High Voltage, Power Supplies

This paper details an investigation into possible technologies suitable for a DC power supply that is comparable in size and voltage output to a Cockcroft Walton Generator, but can produce much greater currents and stores only a fraction of the energy. Early work suggested that the most suitable technologies were those based on conventional transformers, specifically Insulated Core Transformers (ICTs) and High Frequency Cascade Transformers (HFCTs); both of which were investigated further. Different methods have been used to calculate the flux loss in an ICT and ways of reducing these losses investigated. It is concluded that the flux loss of an ICT is too great for use in a practical, high power density, power supply, and that future work in this field should focus on an HFCT based design.
