Open loop and closed loop comparision for single phase Cyclo converter (PID controller)

Abstract

This paper compares the open loop and closed loop system for a single phase Cyclo converter. This paper compares the characteristics like mechanical, speed and torque characteristics of the open loop and closed loop system. In this paper PWM technique is employed along with cyclo converter using IGBT which increases the performance and control of the system. Special advantage of using IGBT in this topology to increases the dynamic characteristics and reduces the total harmonic distortion. The filters are used to reduce the primary harmonics of the system and the secondary or the higher level harmonics. The output for open loop and closed loop was carried out by using MATLAB Simulink. This appear proves the dramatic changes in cycloconverter when comparing with open loop and closed loop using PID controller.
