About Turbo Power Systems (TPS)

In the late 1980s, professor Colin Besant and his team representing Turbo Genset were developing patented axial flux technology to design efficient high-speed generators. The company’s successful developments led to the acquisition of another firm, ‘Intelligent Power Systems’, to deliver power electronics solutions for its generator systems, as well as facilitate its expansion into the railway industry. A merger of these two companies led to the birth of TPS.

Today, the company is renowned for understanding customer needs, designing bespoke solutions, resolving complex issues and delivering results. It has been accredited with a UK Railway Industry Award (UKRIA) for Traction and Rolling Stock, as well as an Elektra award for Power System of the Year.
