Output Voltage Regulated Multiple Output Flyback Converter using PIC and STPIC

Abstract

This work focuses on the process of designing and the utilization of DC to DC fly back converter in closed loop system. Form six decagons conversion of DC to DC has found to be one of the major research areas in the field of power electronics engineering. For getting different levels of output voltage with single input, the advance systems like computer, telecommunication use single input single output dc to dc converter. This system has certain disadvantages like it is less efficient, low power density and the whole system becomes costly. In order to obtained the characteristics of being highly efficient and high power density the power converter with multiple output features are gaining attention. By using this multiple output converter the output is to be regulated for any type of load and source side disturbances. A Multiple Output Flyback Converter (MOFC) is designed, modeled and simulated in Simulink for controlling the output voltage as the desired value. Self Tuned Proportional Integral Controller (STPIC) or Conventional Proportional Integral Controller (PIC) are the two different methods which are utilized for getting the reference signal to obtain the switching pulse of the converter. Different parameters such as Settling Time (Ts), Rise Time (Tr) and Overshoot (OS) are obtained to analyze the performances. The responses of the used method are depicted for comparison of the outputs.
