【摘要】 地铁辅助逆变系统是地铁车辆上的一个必不可少的关键电气部分,它负责为空调机组、通风机、照明、电加热器等交流负载提供稳定的三相380V电源。文章以某市地铁车辆增购项目中,增购的车辆辅助电源变流器为研究对象,研究辅助逆变器的数学建模,为其控制和仿真提供依据。更多还原

【Abstract】 Metro auxiliary inverter system is an essential part of metro vehicles, and it is responsible for air-conditioning units,ventilators, lighting, electric heaters and other alternate current(AC) loads to provide a stable three-phase 380 V power supply. In this paper, the mathematical modeling of auxiliary inverter is studied in order to provide the basis for the control and simulation of the additional auxiliary power converter in the project of metro vehicle purchase in a certain city.更多还原
