本文探讨了在甚高频（VHF，30-300 MHz）范围内工作的DC-DC功率转换器的设计和性能。本文提出了在软开关和软选通条件下，评估和比较甚高频工作时器件损耗的方法。这些方法被应用到一个2 W的谐振升压转换器的开发工作在30 MHz的开关频率。设计的功率级，谐振栅极驱动器，和控制电路进行了详细的处理，实验结果表明该转换器的性能。
This paper explores the design and performance of dc-dc power converters operating in the very high frequency (VHF, 30-300 MHz) range. Methods are presented for assessment and comparison of device losses in VHF operation under soft switching and soft gating conditions. These methods are applied to the development of a 2 W resonant boost converter operating at a switching frequency of 30 MHz. Design of the power stage, resonant gate drive, and control circuitry are treated in detail, and experimental results demonstrating the performance of the converter are presented.
