之前关注过finsix的65W适配器,现在已经生产了,有谁了解VHF的电路拓扑结构不?
MOSFET貌似用的是GaN FET。

大家想想看这个怎么做出来的。

finsix的网站中提到了Class-Φ2 converters,希望有同行能贡献点相关资料。
文章:A Very High Frequency DC–DC Converter Basedon a Class Φ2 Resonant Inverter
finsix网站原文:
“Rising semiconductor losses pose the first challenge as frequency increases. FINsix mitigatesthese losses by utilizing fully-resonant topologies such as the Class-Φ2 converters. Suchcircuits enforce switch commutation by sloshing reactive energy among the switch parasiticsand the circuit elements. This ensures voltage and current as viewed from the switch ports areorthogonal for the switch transition, dropping switching loss to very low levels.”
