Background technology
Power-supply system is one of important load service system of spacecraft, and the DC/DC power supply changeover device (secondary power supply) used in power-supply system is responsible for the secondary voltage that primary power source busbar voltage is transformed to required for secondary electric loading.Therefore, the stability of DC/DC power supply changeover device is directly connected to the power supply quality of secondary voltage.The radiating particle existed in space radiation environment can produce radiation effect to the DC/DC converter be applied in power-supply system, causes device electric property to degenerate or loses efficacy.Therefore, the DC/DC power supply changeover device to spacecraft is selected is needed to carry out capability of resistance to radiation assessment.
At present, DC/DC converter mainly has tatal ionizing dose effects, displacement damage effect (containing needing during optocoupler to consider) and single particle effect, wherein tatal ionizing dose effects and displacement damage effect are cumulative radiation damages, and single particle effect is temporal effect.And the single event burnout in single particle effect is hard damage, directly cause device failure; Single-ion transient state effect also has certain influence to application circuit, but can reduce impact according to the filtering of the situation such as application conditions and Design of Reinforcement.
Although existing DC/DC single particle effect detection system well completes every test mission, to still Shortcomings in sample adaptability, through engineering approaches requirement etc., the space that tool is significantly improved and promotes.Problems existing main manifestations is in the following areas: DUT board cannot the device of compatible different encapsulating structure, the DUT board of existing DC/DC single particle effect detection system develops for the device of concrete packing forms, cannot the device of other packing forms compatible, and clamping part is owing to directly contacting with holder, easily cause the damage of holder, in addition, a traditional body plate shape heat sink, radiating effect is undesirable.
