Abstract

An AC-AC converter system includes transformer arrangements and HVDC converter units on primary and secondary sides of the system, respectively. The system exhibits first and second three-phase AC networks, and the converter units are interconnected via a DC connection. By integrating at least part of two transformer arrangements in one transformer unit, a cost efficient transformer configuration can be achieved.
