Design And Construction

This paper mentions the design and construction of high voltage generator 30 kV using a Fly-back converter. The designed circuit includes the high frequency switching generator which applies power to the primary input voltage of Fly-back transformer. The input power is transformed to be high voltage on the secondary side of Fly-back transformer. The half wave rectifier is constructed for the high voltage direct current (HVDC). Resistive voltage divider is designed and constructed to measure HVDC as well. Moreover, the characteristics of output voltage waveform of the proposed generator is compared with the waveform of the HVDC from Cockroft – Walton circuit.The.comparison.results.show.good.agreement.with.small.difference.

High Voltage Generator

Ultra high voltage STEM has many inherent technical advantages over CTEM. These advantages include better signal detectability and signal processing capability. It is hoped that it will explore some new applications which were previously not possible. Conventional STEM (including CTEM with STEM attachment), however, has been unable to provide these inherent advantages due to insufficient performance and engineering problems. Recently we have developed a new 1250 kV STEM and completed installation at Nagoya University in Japan. It has been designed to break through conventional engineering limitations and bring about theoretical advantage in practical applications.In the design of this instrument, we exercised maximum care in providing a stable electron probe. A high voltage generator and an accelerator are housed in two separate pressure vessels and they are connected with a high voltage resistor cable.(Fig. 1) This design minimized induction generated from the high voltage generator, which is a high frequency Cockcroft-Walton type, being transmitted to the electron probe.
