摘要

针对大电流注入替代高场强辐射进行大电流注入测试时探头阻抗容易发生非线性变化的问题,通过分析大电流注入方法,对现有商用电流探头进行线性度测试。测试结果表明,随着注入功率的增大,不同频率下的线性误差也随之增大。提出了大功率、高线性电流探头的研制方案,研制成功并通过了试验。自主研发的电流注入探头最大承受功率为500w。插入损耗随注入功率变化,线性度好(0.3 dB @ 1 ~ 500 W),满足进行大电流注入(等效高场电磁辐射效应)测试的技术要求。

Performance analysis and development of high-power and high-linearity current injection probes
Aiming at the problem that the impedance of the probe is prone to non-linear changes when applied to the bulk current injection test replacing high field intensity radiation, the linearity test of the existing commercial current probe is carried out by analyzing the method of large current injection. The test results show that as the injected power increases, the linearity error at different frequencies also increases. A plan for the development of a high-power and high-linearity current probe was proposed, and the probe was developed and passed the test. The self-developed current injection probe has a maximum withstand power of 500 W. The insertion loss varies with the injected power and has good linearity (0.3 dB @ 1−500 W). The probe can meet the technical requirements of carrying out bulk current injection (equivalent high field electromagnetic radiation effect) test.
