POWER MANAGEMENT AND POWER FACTOR CORRECTION OF A SINGLE PHASE INDUCTION MOTOR

The purpose of this report is to present the progress and milestones achieved in the course of executing the project on power management and power factor correction of a Single-Phase Induction Motor (SPIM). The main discussion is concerning the work done on the simulation done using SIMULINK and project test setup using the xPC TargetBox for the power management of the SPIM. Using the MATLAB SIMULINK, the simulation of the controlled circuits of PWM Inverter, PWM Signal Generator, Full-Bridge Controlled Rectifier as well as connecting them with a Split Phase SPIM is also discussed. Power factor correction simulation is also discussed at the end of the report. Speed control for SPIM has been used widely around the world, since induction motors are widely used in the industries due to its' rugged construction and controllable speed [1]. Speed of SPIM can be controlled either by frequency control or voltage control, or both. Combining both controls creates a V /f ratio control which is better than using just one of the controls. It provides more efficient and reliability of speed control. In terms of power factor correction, a solution has been found to bring the power factor to approximately 1.0 as load is increased and speed decreased for better efficiency of the motor. At the end of this report, the author prepared several recommendations that can be used for future enhancement of this project
