中文摘要

为实现电力变换器的最优设计,深入理解系统损耗元件至关重要。本文提出了一种通过自动热建模估算电力变换器实际功率损耗的方法,旨在辅助变换器的重新设计、实时监控及功率器件的损耗控制,从而确保系统性能与安全标准。

English Abstract

Achieving the optimal design of power converters requires a deep understanding of the system's dissipation elements to meet the desired performance and safety standards. Once the power converter is designed, it is of key importance to estimate the actual power losses in the real setup, in order to redesign the power converter or monitor and control the semiconductor power losses. With that purpose...
