PURPOSE:To enable continuous supply of small current to the toroidal coil of a Tokamak device, etc. by adding a transformer with low-voltage tap to the side of input of a rectifier supplying DC current. CONSTITUTION:A torus-type magnetism enclosure-system nuclear fusion device such as the Tokamak device sends intermittently DC current obtained by rectifying, by a rectifier 15, AC current generated by a synchronous motor 11 accelerated as a synchronous motor by the AC output of a static type cycloconverter 10 to the troidal coil 2, thereby making the main discharge. In addition, on the side of input of the rectifier is provided a transformer 14 with a tap provided with low-voltage tap on the secondary side as the transformer for the rectifier, and by shifting the input of the receifier, supplies small current continuosly. Accordingly, when a small scale discharge for discharge cleaning is conducted, the small power can be supplied to the troidal coil 2 for a long time in a stable manner. |
