通过设计电源的智能断电控制系统,避免过载导致电器设备的损坏。智能断电控制系统工作原理是通过输出电脉冲信号实现对过载峰值电压的量化分析,传统的断电控制系统设计采用单一道址计数方法进行断电控制,当达到器件所能承受的最高负荷时进行智能断电,该方法受到分离元件的工作温度的影响较大,控制性能不好。提出了一种基于堆栈遍历的智能断电控制系统设计方法,系统主要包括了预处理机动态增益控模块、放大器模块、智能断电滤波模块和电源模块,设计了时钟信号驱动电路、时钟电路、复位电路和动态增益控制电路,在Visual DSP++4.5软件开发环境下进行系统软件开发,仿真实验表明,采用该系统具有较好的智能断电控制效果和精度,断电控制信号的AD能完整采集断电控制请求脉冲信号,有效抑制了温度漂移和基线漂移,性能优越。

The intelligent power-off control system of power supply can avoid electrical equipment damage caused by overload. The work principle of the intelligent power control system is to achieve the quantitative a- nalysis of peak load voltage by the output pulse signal. The traditional power control system is designed by u- sing a single channel access counting method. The traditional power control system design adopts a single channel access algorithm for intelligent powe^off control in case devices reach the maximum load. However, this method is not good control performance for it is greatly affected by the working temperature of the sepa- rate components. This paper proposes a design method of the intelligent power-off control system based on the stack traversal. The system mainly includes the dynamic gain control module, the amplifier module, the intelli- gent power off filter module and the power module. The clock signal driving circuit, clock circuit, reset circuit and dynamic gain control circuit are designed. The system software is developed in DSP＋ ＋ Visual 4.5 soft- ware development environment. The simulation experiments show that the system has good performance and accuracy for the AD of power control signal can completely collect the power-off control request pulse signals, and effectively suppress the temperature and baseline drift.
