3. Evolution of power diagrams in electric traction
3.1 History
We can now better understand the evolution of electric traction through the components that have been used to control the motor from the outset. It's clear that the three-component equation had to be constantly solved:
which traction motor for which mission?
how to control this engine?
which supply voltage?
Initially, the power supply was adapted to the DC motor for lack of anything better, then the motor and its control were adapted to the new high-voltage AC supply voltages, and more recently the performance of control components and power electronics have made it possible to choose the best-performing three-phase brushless...
