Modeling & Simulation of PWM Controlled Cycloconverter FED Split Phase Induction Motor

Abstract

Single Phase induction motors are widely accepted motor due to their energy efficient characteristics. To drive varying mechanical loads for long duty the machine needs to be controlled to increase its efficiency and minimize transient. To control the output parameters of the motor i.e., Speed and Electromagnetic torque the fixed frequency of the system is varied for which a Cycloconverter is employed along with PWM technique to increase the system efficiency. The Cycloconverter is built on with IGBT due to its improved dynamic performance and efficiency and reduction in the level of audible noise. Low driving power and a simple drive circuit due to the input MOS gate structure. It can be easily controlled as compared to current controlled devices (Thyristor, BJT) in high voltage and high current applications. With the help of PWM the output voltage control can be obtained without addition of any external components and PWM minimizes the lower order harmonics, while the higher order harmonics can be eliminated using a filter
