摘要
介绍了一种实用的物理实验专用线性可调稳压直流电源。该电源由可调三端稳压、可调基准电压、限流电路等构成,可提供0~12 V连续可调电压,输出电流限制在100 mA,适用于大学物理实验中二极管伏安特性测量、三用电表的设计与制作等设计性实验,起到对实验器件和仪表的保护作用。
An applied adjustable liner D.C stabilized source used in physical experiments is designed,which is formed by Three-terminal adjustable voltage regulator,adjustable precision shunt regulator and current limited circuit.Continuous output voltage from 0 to 12V and 100mA short current can be supplied.It is very useful in the physical experiments such as measuring the diode volt-ampere characteristics and design of the multi-meter.By using this supply,the experimental sample devices and the meters can be protected effectively.
