浮地模式AC宽工作电压范围的爆闪式信号灯设计

A design of strobe light formula based on floating ground converter AC wide voltage range of work

设计了一种基于浮地工作模式的爆闪灯,该爆闪灯采用MK6A11P单片机控制,通过专用芯片HV9910组成浮地模式的Boost变换器给浮地电容充电,并由分压电阻检测浮地电容的电压,以此控制PWMD端的电位实现对频闪管的控制.实验证明,这种爆闪灯可在40~250V的宽电压范围内稳定工作,且因具有结构简单、成本低廉的优点,有望替代现有在48、110、220V电压下工作的同类产品.

This paper design a strobe light based on floating ground converter. The strobe light is designed using MK6A11P single-chip microcomputer, the polder capacitor is charged by the polder model Boost con- verter which is composed of a dedicated chip HV9910, and the voltage of the polder capacitor is detected by the divider resistance, thus to control the potential of the PWMD terminal, to achieve control of the strobe. The experimental results show that the strobe light can stably work in widely range of AC 40-250 V, and it has the advantages of simple structure and low cost. Therefore it may replace the product which working in AC voltage 48 V, 110 V, 220 V.
