摘要
本文在归纳总结LLC谐振变流器现有同步整流技术的基础上对各技术的优缺点进行了详细的分析和比较,并提出了新型的一次侧电流采样方案以及一种应用于倍压整流结构的新型电流型同步整流技术。除此之外,本文还从电力电子系统集成的角度提出了新型的单封装结构同步整流技术解决方案。
Based on the existing synchronous rectified LLC resonant converter reviewed in this paper, advantages and disadvantages are analyzed and compared in detail. A novel primary-side current sensing strategy and a new current driving method for voltage-doubler rectifier are presented. Finally, this paper proposes a family of novel single-package structure for synchronous rectifier from the view point of power electronics integration to improve the performance further.
