摘要
结合DC/DC变换器的工作原理,介绍了其中子失效模式以及试验环境,讨论了DC/DC变换器中子试验的在线测试技术,提出了解决长线造成测量误差的具体办法。在实际应用过程中,对变换器进行了电压校准,达到了在0~20V范围内电压测试误差不超过±50mV。
According to the principle of DC/DC converters,the failure mode of neutron irradiation and the environment of neutron irradiation experiment were introduced.Technologies of on-line testing in neutron irradiation experiment for DC/DC converters were discussed.By using voltage calibration,the deviation of measured values caused by long term interference was reduced.In the practical application,the maximum voltage measurement error was±50mV in the range of 0~20V,which had met the requirements of system＇s accuracy.
