Embedded Power Supply Design Method Based on the Embedded Electrical Components Sensitive Model

针对工业控制中嵌入式电源的应用广泛,应用的环境复杂,大中小型的电源功耗不断的提高,急需降低电源的能量消耗的问题。提出了基于电器元件敏感模型的降低嵌入式电源能耗的方法。利用工业控制电源工作的时候频率属性和工作电压变化规律,计算出电源功耗最低的时候,元器件和敏感性的平衡点,使得电源在敏感性最优状态下工作,进而达到降低能耗的目的。实验表明。利用这种敏感性模型,能够有效降低以ARM7和ARM9为核心芯片为主的嵌入式电源的功耗,取得令人满意的效果。

Embedded in the industrial control in the power of the widely used, the application of complex environment, and small power consumption continuously improve, in need of reduce the energy consumption of the power supply prob- lem. Based on the electrical components of the sensitive model embedded power energy consumption reduction. Using in- dustrial control power supply working frequency properties and working voltage variation, calculated the lowest power consumption, components and sensitivity of the balance, makes the power supply work in the sensitivity of the optimal condition. To attain the goal of reducing energy consumption. The experimental results show that. By using the sensitivity of the model, can effectively reduce the ARM7 and ARM9 as the core chip embedded power consumption of the Lord, obtain a satisfactory result.
