   Medium-frequency transformer  evaluated  
The main transformer contributes considerably to losses in traction system (especially in 16,7 Hz systems). Modern power electronics allow for a more efficient and much lighter alternative: the medium frequency transformer operating at 400 - 800 Hz or comparable frequencies.
Technology field: Optimisation of traction technologies
