中文摘要

近年来，甚高频(VHF)变换器备受关注。然而，由于其丰富的寄生参数和复杂的谐振环节，系统建模面临巨大挑战。本文以开关控制的VHF谐振升压变换器为例，提出了一种考虑多种寄生参数的精确建模与分析方法。

English Abstract

In recent years, very high frequency (VHF) converter has attracted much attention. However, with rich parasitic parameters and complex resonance links, there are some great difficulties to the modeling of such systems. Taking the on-off controlled VHF resonant boost converter as an example, this paper presents an accurate modeling and analysis method that considers multiple parasitic parameters. F...

VHF（甚高频）技术是提升功率密度和实现小型化的前沿方向。虽然阳光电源目前的主流产品（如PowerTitan储能系统、组串式逆变器）多处于高频段而非甚高频段，但该建模方法对于优化高频磁性元件设计、降低寄生参数影响具有重要的参考价值。随着宽禁带半导体（GaN/SiC）在户用光伏及小型化充电桩产品中的渗透率提升，掌握此类高频精确建模技术，有助于阳光电源在未来实现更极致的功率密度提升，并为下一代高频电力电子产品的研发提供理论储备。
