This paper introduces the application of AC drive system composed of speed closed loop and slip frequency control traction inverter in mining electric locomotive. This system uses high-performance digital signal processor TMS320F240 to control asynchronous traction motor, and the generation of PWM pulse wave is based on space voltage vector (SVPWM) pulse width modulation. It enables the electric locomotive to achieve constant torque starting and constant power operation traction characteristics.
