An HVDC equidistant converter control model Struyk, Emile

Abstract

This thesis presents the design and construction details of a physical model of a six-pulse HVDC converter suitable for steady-state studies. The converter rack has been built to facilitate simple testing and breadboarding. A digital equidistant firing angle controller has been constructed for the converter-rectifier current control. An electronic phase-locked loop has been used to generate an accurate control frequency. Modifications have been suggested to make the rectifier, fully operational. The control system has been constructed for future inverter control circuits and possible computer control.
