QB-940/10 traction transformer
QB-940/10 traction transformer
QB-940/10 traction transformer is suitable to be used with Four quadrant traction converter to supply power to Four quadrant traction converter, or the traction converter conversely supply power to the traction transformer by using SPWM modulating wave and feedback the power to grid. It is widely used in electric locomotive test stand and power generation system which uses converter.
