Title:
TRANSFORMER CONFIGURATION FOR A HVDC BACK-TO-BACK CONVERTER
Document Type and Number:
WIPO Patent Application WO/2013/124374
Kind Code:
A8
Abstract:
An AC-AC converter system (500) comprises transformers and converter units (540a, b) on primary and secondary sides (550a, b) of the system, respectively. The converter system is connected to first and second AC networks (550a, b) and the converter units are interconnected by means of a DC link (560, 562). By integrating at least part of two transformers connected to the first and second network respectively into one transformer unit (530a-c), a cost efficient transformer configuration can be achieved. The converter system is preferably a back-to-back HVDC sytem.
