摘　　要：本文探讨利用双DC-DC变换器去解决单级DC-DC变换器在宽电压范围工作时开关效率降低,开关器件不能正常工作,甚至损坏的问题。在现有信号灯的基础上,设计出一种寿命长、适应宽电压范围、功能齐全,便于生产、管理、使用、维修的爆闪式警示信号灯。The paper make use of Double DC-DC convertor to resolve some problems of current DC-DC convertor that work in the breadth voltage, these problems include lowering efficiency of switch, switching device working inordinately so much as damage. On the base of current signal lamp,.it designs a explosion-flashing alarm lamp with a long life ,breadth working voltage , fully functions and convenient in production, management, use and repair.

关 键 词：DC-DC变换器 开关效率 爆闪式
