用于多系统机车直流电压匹配与纹波抑制的可重构线路侧变换器

The multisystem locomotive traction drive system is fed by different kinds of railway traction power supply systems (TPSSs). The direct connection of the dc TPSSs and the traction inverter are broadly adopted. However, the dc-link voltage is influenced by the variable and fluctuant catenary voltage, therefore wasting the capacity of the devices, complicating the wiring of motor as well as reducing...
