高精度交直流电流校准源研制

The Development of High-precision AC-DC Current Calibration Source

为满足交直流电流表量值传递/溯源的需要,研制一种源、表一体化的高精度、大功率、宽频响的交直流电流校准源。本文介绍了各部分电路的原理及特点,通过合理配置各部分电源以实现所要求的技术指标。

In order to satisfy the need of the traceability and value of a quantity transfer of AC-DC ampere meter, the paper developed the AC-DC current calibration source of high-precision, high-power and broadband frequency response, which is unification of the source and standard instrument. It introduced the various parts of the principle and characteristics of the circuit, through the rational allocation of the various parts of the power to achieve the required technical specifications.
