Abstract :
The irradiation response of DC-DC power converter was studied using X-ray source with whole and local irradiation method. It was indicated that the irradiation response of the different part of circuit was represented different effect. The VDMOSFET of DC-DC power converter was tremendous irradiation affected, and PWM and Shottky diode was exiguous affected, and the trend of DC-DC power converter optical-coupler parameters affected by optical-coupler was reversely with other part of DC-DC circuits.
