The primary side constant current control method is widely adopted for LED driver and portable device charger applications due to its simplicity and low cost.However,most of the primary side CC control method now is only suitable for discontinuous current mode (DCM) mode or critical conduction mode (CRM).This paper proposes a general primary side control method suitable for both continuous current mode (CCM),CRM and DCM,which can be adopted most of the topologies like Buck,Boost and Buck-Boost (or Flyback).

2020年4月,永嘉陡门溪发现了雕岩谷地貌景观,这是浙江省境内第一个被考察论证的雕岩谷。雕岩谷是2018年才正式命名的一种特殊的河成地貌景观类型,其成因与河水侵蚀、壶穴贯通有关。从羚羊谷到雕岩谷喜欢摄影的人一定不会错过美国亚利桑那州印第安部落的羚羊谷,那里以野羚羊出没而得名,是世界上著名的摄影基地。羚羊谷的岩层有着独特的弧形构造、波浪形线条和耀眼的红色,拍摄效果非常出彩。它独特的地貌甚至能为设计师
