Abstract

The traditional 24-pulses rectifier for traction power system of urban rail transit was not agree with environment friendly idea as a result of unidirectional power flow,faulty harmonics characteristic and uncontrolled output voltage.In this paper,several original traction power system were proposed by applying PWM technology,advantages and disadvantages of which were pointed,as well as the respective application situation was analyzed.All the results showed the new direction for traction power system of urban mass transit.
