Comparative Analysis of Optimization Techniques for Buck ZVS Quasi-Resonant DC-DC Converter Design

A Buck Zero Voltage Switching (ZVS) Quasi-Resonant DC-DC Converter is the subject of this research, which attempts to evaluate and contrast the different optimisation methodologies that were used in the model-based design of the converter. Both the amount of time that is necessary for each optimisation procedure and the degree to which they guarantee the performance of the power electronic device are taken into consideration during the comparison. In order to construct quasi-resonant DC-DC converters in the most effective manner possible, the primary objective is to offer a variety of ways that make use of mathematical software. Because their creation is dependent on computational procedures, which sometimes need numerous iterations to finish, these topologies were selected as the best option. A target function reference curve was used in order to achieve optimal performance of the output voltage. Using this method, optimisation may be accomplished without the need for a comprehensive design of the device. Instead, the determination of starting values and parameter intervals is accomplished by relying on base ratios, design limitations, and previous experience gathered. The optimisation of the reference curve of the output is the primary emphasis of this technique, which provides a substantial benefit over other objective functions such as minimising losses or maximising efficiency.
