用L6562+IRF840做APFC恒压控制,
用L6561+IRF840(暂时)做BUCK零电流控制(限压,最低频率保护等,这部分复杂了一点),
IRS2453+4xIRF740全桥驱动(喜欢用新的器件),
Viper12A做直流电源(便宜/稳定),
CD4060/74HC4060做定时器(喜欢数字电路,不喜欢电解定时),
LM2904双运放恒功率控制,LM2901四比较器用于保护电路,没有用单片机(经济版,下次设计一个带ADC单片机的,呵呵)
电感都用EE20x11core,估计损耗发热还可以,
外壳准备与philips的差不多大.
原理图画的比较乱,在画PCB还没整理,
供大家参考,
欢迎讨论.
