HVDe BRIDGE GENERATOR 40 kV 5 rnA

Abstract

This paper presents the design and construction of HVDC Bridge generator rated 40 kV at 5 rnA by using voltage multiplier bridge type comprising of2 stages operation which is constructed at high voltage laboratory in the faculty of electrical engineering, Khonkaen University. This HVDC generator has improved the voltage drop in the circuit which is better than the case of using voltage
multiplier Cockcroft-Walton type that employed higher stage than 2 stages .From the design and tests, this HVDC generator confirms that HVDC Bridge generator has voltage drop less than HVDC Cockcroft-Walton generator 25% at 2 stages, 25% at 3 stages and 37% at 4 stages respectively. The results obtained from calculations and measurements have been shown to agree well with each other.
