Abstract

DC/DC power converters are core devices of power system in charge of convert motherboard voltage into secondary supply voltage, and it plays pivotal roles in supporting aircrafts on-orbit missions. As the size of the integrated circuit becomes smaller and smaller, the power supply voltage of the device is getting lower and lower. However, the Single Event Transient (SET) from DC/DC power converters in the space application will cause disturbance to the lower supply voltage devices, even burn-down the device seriously, which brings serious security problem to the power supply device. In this paper, SET radiation test has been carried out under the Kr ions at HIRFL cyclotron. The result has been analyzed with triple and double output DC/DC power converters under the different input voltages and load currents. The width and amplitude properties of SET waveform are analyzed. The research can be treated as a reference for converters in space application and anti-radiation design.
