The Korean Domestic Agency (KO-DA) signed a contract with an industrial consortium for the ITER AC/DC converters on 12 August, 2011, following a call for tender launched in June. The Procurement Arrangement for these components was signed back in March. A representative of ITER Organization participated in the technical evaluation meeting for the supplier selection process.

The selected consortium is formed by the converter firm Dawonsys Co., Ltd. and the transformer firm Hyosung Corp. The contract is expected to run for seven years. The converters for toroidal field, central solenoid, vertical stability and correction coils including master controllers, a dummy load, and spares are deliverables of the contract that covers the design, fabrication, site assembly and installation, and technical assistance during the circuit integrated test.

Korea has now awarded contracts on more than 80 percent of its in-kind contributions to the ITER project.

Dawonsys is specialized in the power supplies for fusion, accelerators, traction and heavy industries and has provided large-current power systems for superconducting magnets as well as the high-voltage power system for neutral beam injection, electron cyclotron heating, lower hybrid current drive and electron cyclotron current drive at the KSTAR Tokamak.

Hyosung is a global-solution power system supply company and a leading manufacturer of power transmissions and transformers. It recently reinforced its capacities with IT-based power automation and Smart Grid including power monitors and prevention system. On the basis of various technical skills and experience, Hyosung supplied Ultra High Voltage (UHV) power transformers for KSTAR.
