Abstract :
This paper presents the performance analysis of an improved power quality AC-DC converter (IPQC) fed vector controlled induction motor drive (VCIMD) for electric multiple units (EMU) application in electric traction of Indian railways. The IPQC enhances the input power factor close to unity and also reduces the total harmonic distortion (THD) of AC mains current. The converter provides bi-directional power flow capability during regenerative braking resulting in energy efficient operation of the drive. It also provides constant DC-link voltage during transient and steady state conditions. Detailed modeling and simulated results of the proposed converter fed induction motor drive are presented to demonstrate the features of improved power quality and energy conservation
