| 摘 要： | 24脉波二极管整流器等传统直流牵引供电系统成熟可靠,但由于其能量无法双向流动、谐波特性欠佳、直流电压不可控等缺陷,与高效节能环保的发展理念不符.通过将PWM整流技术应用到直流牵引供电系统,提出了多种新型电路拓扑,分析了各自的优缺点及应用场所,为直流牵引供电系统的发展提供新思路.

| 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. |
