AcknowledgementsThe author would like to gratefully acknowledge the guidance and encouragement of Mr. Billy Chow, the project supervisor, whose contributions further stimulated my interest in further investigation questions related to circuit simulation. and feed me ideas to improve the design and testing process. Success indicates the correct direction of this project.Executive SummaryThe aim of the project is to research and analyze the DC DC converter for suitable application of spool gun. In this project, DC converters have different types and characteristics. This introduces four types, namely Buck, Boost, Buck-Boost and Cuk converters, which have been studied and compared. In the 4A design, the circuit implementation of the high voltage DC boost converter was simulated using PSIM software. PSIM software is widely adopted in universities, consultancies, research centers, enterprises, etc. This software is the fastest simulator for power electronic circuits. It is capable of simulating large and complex power converters and control systems in a short time. Following the development of the 4B design, the circuit will be modified to improve the ripple waveform of the output and improve the feedback circuit to control the output voltage. In addition, the converter is adopted based on measurements and comparisons between power circuits in simulation time.Table of ContentsNo. Description page1. Introduction 42. Background 53.

Therefore, design the equivalent integrated circuit suitable for high voltage DC DC boost converter. Then, the output waveform of the circuit is designed and simulated successfully. But it is the combination in the boost converter that makes the output waveform simulation results a problem for the boost converter. The voltage and current of the output stage continue to increase, which has not stopped for a long time. In 4B design, it is necessary to improve the problem because the voltage and current of the output stage cannot stop and the ripple waveform. This requires completing the design, improvement and simulation of the booster converter, final project presentation, demonstration and final project report writing work. Although it is a big challenge as one has to work during the day and can only spend night on the project..
