The vast majority of EV traction motors must be supplied with sinusoidal 3-phase alternating current with the frequency proportional to RPM, and the overwhelmingly favorite way to do this is with a triple half-bridge voltage source inverter, or VSI. In this topology, each bridge switch can connect its output terminal (i.e. motor phase winding) either… Read more »
