Abstract
This paper presents the source current wave shaping of variable frequency induction motor drive system using Unity Power Factor (UPF) rectifiers. Rectifier fed induction motors are the essential part in industrial applications because it is difficult to convert the input supply frequency directly for variable frequency drive. Hence, it is necessary to connect the AC/DC converterfollowed by DC/AC converter system to vary the input supply frequency and magnitude of the motor. The conventional rectifier draws a non-linear current and injects harmonics into the power system network. The two different UPF rectifier models are proposed here for controlling the amount of harmonics injected into the AC power system to increase the input power factor. The proposed UPF rectifier-fed induction motor drive systems reduce the source current THD and maintains the DC-link voltage as constant. The performance of Vienna rectifier, PWM rectifier systems are compared with a conventional three phase bridge rectifier-fed Induction motor drive.
