Description

technical field [0001] The invention relates to the technical field of space environment radiation resistance test, in particular to a radiation effect measurement and control system of a DC-DC (Direct Current-Direct Current, direct current to direct current) power supply module. Background technique [0002] There are a variety of high-energy ray particles in the space radiation environment, which will pose a threat to various spacecraft such as satellites working in space. Particle effects, which lead to device failure. DC-DC power modules are widely used in various spacecraft. Due to the single event effect caused by the radiation damage of the DC-DC power module, the characteristics of the internal components of the spacecraft will fluctuate or even burn out, which seriously threatens the life and reliability of the spacecraft. sex. [0003] Single event effects of DC-DC power modules mainly include single event burnout, single event lockup, single event function inter...
