0—10V高稳定直流电压基准的研究

介绍一种0～10V可调直流电压基准的设计。该电压基准通过对电压平均技术和双通道脉宽调制分压技术的研究与应用，既可使用内部高稳定直流电压基准，也可外接高稳电压基准实现0V～10V直流电压的连续输出，保障了直流电压基准输出的连续性与稳定性，其10V输出稳定度指标优于2·10^-6／y（恒温条件下），可广泛用于高水平电压标准器的研制。

Research of High Stability 0-10 V DC Voltages Reference Element

Introduces the design of a 0 - 10V DC voltages reference element. The voltage reference element can immediately use the inner part high stability dc voltage basis, also can circumscribe continuous exportation that the high stability voltage basis carries out the output of 0 - 10 V. Relies on the tech- nology of the average voltage and double pulse width modulate research and applications separately, guarantee the voltage reference element output＇s consecution and stabilities, it＇s stability of 10 V outputs is better than 2 . 10^-6/y（ under the constant temperature condition） , can used for standard of high level electric vohage＇s research to manufacture extensively medium.
