Application of Modular Power Converter in AC Traction
Zhang Liwei Huang Xianjin Sun Hu You Xiaojie
Currently, ac traction system, composing of ac-dc-ac voltage power converter and induction motor, has become the mainstream of electric drive technology for electric locomotive, electric multiple units and articulated motor coaches. The core of ac traction system is power converter. This paper gives analysis and summary to the features of modular power converter (MPC) designed by ADtranz. With the development of power electronics and micro-processor, the modular and distributed control system is the trend for power converter.
