Fuzzy Controlled Multiple Output Dc to Dc Flyback Converter with Output Voltage Regulation

Abstract

The aim of this paper is to design and closed loop control implementation of a DC to DC Flyback converter with multiple output features. DC-DC Conversion technology is the major subject area in the field of power electronics engineering and drives and has been under development form six decades. Most of the advance systems like telecommunication and computer systems use the single output DC-DC Converter for different levels of voltage in the same system, which limits the efficiency, power density and increases the cost of the whole system. To achieve the features like high efficiency and high density for advance systems Multiple Output DC-DC Converter (MODC) are gathering much attention, and most of the research work is going to get the regulated multiple outputs, for different application like computer, electric vehicles, aircrafts etc. A MATLAB/Simulink model of a Multiple Output Flyback Converter (MOFC) is developed to get the regulated multiple output voltage. Two different control techniques have been employed such as Proportional Integral Derivative Control (PIDC) and Fuzzy Logic Control (FLC), to achieve the same for normal and disturbances cases and its performance is then estimated in terms of various parameters like Rise Time (Tr), Settling Time (Ts) and Overshoot (OS). The comparative results clearly reveal the better response of the proposed approach.
