Electrical wire explosion (EWE) is characterized by great current density and rapid metal heating, which make itself an ideal tool for nano-materials manufacturing technology The EWE requires a high voltage electric-energy source In the current experimental set-up a high voltage capacitor is used for the purpose. Hence, a power supply that is capable of charging the capacitor to a target voltage is required One of the special requirements is the precise controllability of the stored energy level in the capacitor. Through this study a high voltage capacitor charger using a series resonant converter technology has been developed for the production of nanosize powder A load capacitor of 32u.F can be charged up to 20kV by the developed capacitor charger and discharged through a gap switch and a copper wire.
