Abstract

The irradiation response of a DC-DC power converter was studied. During the test, the characteristic parameter of DC-DC power converter such as input current and output voltage increased slowly with empty load, and DC-DC power converter was unsteady and the characteristic parameter was strongly influenced by the total-dose when fully loaded. It was indicated that failure of DC-DC converter was due to the source and drain of VDMOSFET fused together because of over power.

DC-DC功率变换器的辐照效应及失效分析

研究了直流-直流电源变换器的辐照响应。在试验过程中，DC-DC功率变换器的输入电流和输出电压等特性参数在空载时增长缓慢，且DC-DC功率变换器不稳定，且满载时其特性参数受总剂量影响较大。分析表明，DC-DC变换器的失效是由于电压过大功率导致VDMOSFET源极和漏极熔接在一起造成的。
