TJ-II:Power supply
The generation of the magnetic field during a TJ-II discharge requires a total amount of power of almost 50 MW. This power is supplied by the national grid and a 140 MW flywheel generator (100 MJ, 15 kV, 100 Hz). As the TJ-II loads require a direct current, a set of thyristor converters, transformers and circuit breakers are used for each coil system. The power requirements range from 5 kA (100 V) to 32 kA (1000 V). The heating systems (ECRH and NBI) load the power supply with additional 15 MW. [1] [2]
