Design and construction of a 12kV D.C. power supply

Abstract

An experimental work on a modified version of the so-called Cockroft-Walton type voltage multiplying rectifier was carried out. This involved the study of the factors governing the output voltage of the Cockroft-Walton multiplier, designing a multiplier based on these factors that can yield the targeted output voltage of over 10 kV, and the construction of a 12-kV d.c voltage generator. Essentially, the constructed generator is a modified 32-stage Cockroft-Walton type voltage multiplying rectifier. It is suitable as a power supply for the nitrogen laser. It can also be used in particle acceleration. The results of the study of the factors governing the output of the Cockroft-Walton multiplier, the components type and specification, and the construction and performance of the generator are presented and discussed
