Electric traction drive system is the key and difficulty of the equipment of metro cars. In the traction drive system, train traction control is the most important part. Its operation reliability directly affects the safety and stability of trains. In the train traction control, SVPWM modulation method has wide application. This paper introduces the principle of SVPWM and analyzes the feasibility of implementing pulse width modulation technology by FPGA, introduces the specific implementation strategy of the pulse width modulation method, and then verifies the correctness of the theoretical research by amounts of simulations and tests.
