INTEGRATED CONTROL STRATEGIES FOR NON-IDEAL FORWARD CONVERTER

Abstract

This thesis sheds light on the rising demand for highly efficient power conversion electronics, putting emphasis on the role played by Forward converters. These stand out the primary objective of this scholarly thesis revolves around the comprehensive examination of the Non-ideal Forward converter through the application of small signal analysis, and the tailored design of its control techniques, ultimately aiming to elevate performance and ensure stability. The dc-dc isolated forward converter is a widely utilized power converter because of its great efficiency and ability to convert voltage both up and down. However, the efficiency and stability of the converter may be affected by the presence of parasitic elements such leakage inductance and diode junction capacitance. These components cause distorted waveforms and voltage spikes, which eventually affect the converter's performance and output voltage regulation. In order to overcome these difficulties and achieve voltage control in the forward converter. A minimal phase system that includes parasitic elements in a closed loop. This abstract investigates a variety of mitigating strategies. Analysis is done on the converter's stability using a PI controller and ANFIS controller which is inserted into the feedback path. Advanced control techniques, including feedforward compensation optimization, can be used to improve the forward converter's control loop performance and offset the impacts of parasitic elements.
