Abstract

DC high voltage is one of the means used in a variety of insulating material testing and laboratory equipment. In addition, direct current high voltage transmission lines are used in electrical power. Thus, the DC high voltage is very necessary existence. This study aimed to design and implement a miniature prototype DC high voltage generator with the modified multiplier circuits. In this design, the AC low voltage was rectified alternating first, and the DC voltage was multiplied by using the modified multiplier circuit. The circuit output voltages were DC high voltage forms. The DC output high voltages were measured by using a digital storage oscilloscope through a voltage divider. Thus, various DC high voltage waveforms could be measured and recorded by the storage oscilloscope and the data were transferred to the computer. In this design, it was realized four stages of dc high voltage multiplier, where it was yielded 6185 Volt dc with the input of 600 Volt rms ac, on the no load condition. The average ratio of the dc voltage to rms ac input voltage was 10.76. The average ripple of dc output voltages was 1.134% on the no load condition.
