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.
