ITER (International Thermonuclear Experimental Reactor) is an international joint research and development project which is funded by seven countries and the largest project in the history to develop fusion energy. This joint development project is carried out to develop fusion energy to overcome the problems of oil depletion and global warming. In order to build 5.08 billion euro worth of fusion research at Cadarache, France by 2015, the research results of DIII-D of USA, EAST of China, KSTAR of Korea, JET of EU, JT-60 of Japan, Tore Supra of France shall be used. Through these results, the technological and engineering possibility of utilizing fusion energy shall be confirmed, and demonstration and first commercialization are targeted to finish by 2035~2040.

ITER is designed to produce electric power of 500 MW by maintaining fusion of the compound of 0.5 g of deuterium and tritium in the tokamak of 840 m3 for 1,000 seconds. Research on burning plasma operation technology which makes continuous fusion reaction shall be focused through ITER.

PLASPO started to develop power stacks and drivers for 60MVA high power conversion devices in 2008, which will be completed by 2015.
