Power Factor Correction Using Predictive Current Control for Three-phase Induction Motor Drive System

Abstract

This paper presents the study of a three phase pulse width modulation inverter-fed induction motor drive with single phase utility input, with and without a power factor correction circuit (PFC). The PFC circuit is controlled with the proposed predictive current control. The effects of the PFC circuit on the magnitude of the input current, harmonic contents and input power factor of the AC drive system are studied. A comparative study of simulation and experimental results for the AC. drive system, with and without PFC circuit, is carried out. The experimental implementation of PFC control of the boost converter controlled three-phase IM drive system using DSP controller board DS1104 is achieved using the proposed predictive control. The proposed PFC control method used to achieve a low input line current harmonics, for obtaining a good power quality with a fast dynamic response for output voltage and line current.
