Abstract
With the continuous development of power electronics technology, power electronic converters are becoming increasingly common in industrial and household applications today. As the core component of the converter, the loss of the switch tube not only directly affects the performance and stability of the converter, but also directly affects the cost and reliability of the converter. Therefore, in power electronic converters, the analysis and optimization design of switch losses have become increasingly important. In this article, we will first introduce the basic concepts and functions of power electronic converters, then conduct a detailed study of the working principle, classification, and calculation methods of switch tubes. Finally, we will elaborate on the optimization methods of switch tube losses and the impact of converter design schemes on switch tube losses. Based on practical cases, we explored the selection of circuit topology, control strategies and parameter optimization, heat dissipation and voltage matching techniques, as well as the specific issues of switch losses in different types of converters. These methods and techniques have significant guiding significance in the design and optimization process of power electronic converters, which can improve the performance and reliability of converters, reduce production costs, and further accelerate the development of power electronic converters.
