摘　　要：稳压电源是任何电子设备都必不可少的部分,线性稳压电源因为其低纹波、低噪声、高稳定性和快速响应等特点被广泛应用于各个领域。开关电源因其极高的效率和较小的体积成为当今研究热点,但其纹波干扰较大,因此在很多场合都必须使用高精度的线性稳压电源,本文设计制作了一种高精度且电压可调的线性稳压电源,电压调整范围从10V^30V。经实验结果表明,本文设计的可调线性电源稳定性极高、输出电流大,纹波约为输出电压的千分之一,具有很好的推广应用价值。Regulated power supplies are an integral part of any electronic device.Linear regulated power supplies are widely used in various fields due to their low ripple,low noise,high stability and fast response.Switching power supply has become a hot research topic because of its high efficiency and small volume,but its ripple interference is large.Therefore,high-precision linear regulated power supply must be used in many occasions.In this paper,a high precision and adjustable voltage linear regulated power supply is designed.The range of voltage adjustment is from 10 V to 30 V.The experimental results show that the adjustable linear power supply designed in this paper has high stability,high output current,and about one thousandth of the output voltage ripple.It has good application value.
