Abstract
In view of problems of complex structure of main circuit and limited power and voltage existed in traditional traction system of AC-DC-AC electric locomotive,a traction converter for electric locomotive with single-phase AC input and three-phase AC output was designed based on structure of modular multilevel converter using full bridge sub-module.The traction converter can drive traction motor directly,so as to eliminate vehicle-mounted step-down transformer and reduce complexity of traction system of electric locomotive.A constant AC voltage control strategy in outer loop and direct current control strategy in inner loop was proposed according to mathematic model of the converter established in two-phase synchronous rotating dq coordinate system.The simulation results verify validity of the converter and the control strategies.关键词
