In railcars, the energy losses in power electronic equipment such as vari-able voltage variable frequency (VVVF) inverters for propulsion and auxiliary power supplies have been steadily reduced.
Customer Service
A VVVF inverter is an electronic device that controls the speed and torque of AC motors. It does so by varying the voltage and frequency of the power the motor receives.
Customer Service
These inverters convert incoming DC power to AC power as well as control the amount of power (voltage and frequency) being supplied in accordance with the train''s speed, etc. In addition, these
