Abstract :
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.
