Tokamak Energy has recently announced a breakthrough design of cryogenic, or very low temperature, power electronics technology for the high-efficiency operation of its superconducting magnets. This will result in reduced costs of future fusion power plants – which is key to commercialising and scaling the technology.

The power electronics team at Tokamak Energy has developed a novel power converter inside a vacuum cryostat. Successful tests completed last month have demonstrated a 50% reduction in the power required for cooling HTS magnets.
