摘要

利用x射线源研究了DC-DC功率变换器的辐照响应。在试验过程中，DC-DC功率变换器是不稳定的，输入电流和输出电压等特性参数受总辐照剂量的影响较大。研究表明，辐照对DC-DC功率变换器中的光耦合器有很大的影响，而VDMOSFET的爆发是导致DC-DC变换器最终失效的原因。

The irradiation effect of DC-DC power converter under X-ray

The irradiation response of DC-DC power converter is studied using X-ray source. During the test, DC-DC power converter is unsteady and the characteristic parameter such as input current and output voltage was strong influenced by the total-irradiation-dose. It is indicated that optical coupler in DC-DC power converter is tremendous affected by irradiation, but the ultimate failure of DC-DC converter is due to the VDMOSFET broken out.
