摘要
现有的交流爆闪灯采用电容降压方式给能量储存电容充电后对频闪管放电的方式工作,这种方式结构简单、工作稳定,但功率因数很低,且只能在210~230 V的很小的电压范围内工作,当使用在110 V时变更为倍压整流方式设计,因此使用不便,产品种类多也管理不便。因此设计了一种基于SEPIC变换器的爆闪灯,这种爆闪灯可在交流40~260 V宽电压范围内稳定工作,由于采用APFC方式工作,因此具有近似为1的功率因数。同时利用MK7A23单片机进行控制,因此整体电路简单、工作性能稳定可靠,大大提高产品的使用范围,减少管理维护成本。
Existing way of communication with flashing lights using capacitance step-down to energy storage capacitor charging mode of stroboscopic tube discharge after work, this way has simple structure, stable work, but the power factor is low, and can only work in the little working voltage range of 210N230 V, when using more times in 110 V in pressure rectification method is designed, so difficult to use, product variety and management more inconvenience. So we design a flashing lights based on SEPIC converter, the flashing lights at 40-260 V AC voltage stability within the scope of work, as a result of APFC way to work, so it is the power factor of the approximate to 1. Using MKTA23 single-chip microcomputer to control at the same time, so the whole circuit is simple, stable and reliable work, greatly improve the using range of products to reduce maintenance cost management.
