资料介绍

为了克服传统直流升压电路体积大、能耗大的缺点,设计一种基于NE555的直流升压电路。该电路具有功耗低、结构简单、变换效率高等特点。利用Proteus电路仿真技术,对该直流升压电路模型进行仿真分析。通过改变影响直流升压电路输出的两个关键因素,得到电路输出电压的变化规律。通过实验验证,设计电路达到了预期目标。实验结果表明,在保持脉冲频率和储能电感的电感量一定的情况下,负载电阻和控制脉冲的占空比的增加,将导致电路输出电压增大。

To overcome the disadvantages of large volume and high energy consumption of traditional DC boost circuit,a DC boost circuit based on NE555 was designed. The circuit has the characteristics of low power consumption,simple structure and high conversion efficiency. The DC boost circuit model was analyzed and simulated by Proteus circuit simulation technology. The change rules of output voltage was obtained by adjusting the two key factors influencing the output of the DC boost circuit. It was verified by the experiment that the designed circuit can meet the expected objective. The experimental results show that the increase of the load resistance and duty ratio of control pulses will cause the increase of the circuit output volta...
