Q: what is a VVVF propulsion and what's its purpose?

A: The VVVF Inverter converts the Direct Current (DC) power from the OCS (Overhead Catenary System) to Alternating Current (AC) to power the train's electronic systems (doors, control panel etc.) and mainly powering its traction motors on the bogies making the train move and propell on its own.
