通过对故障树进行试验和排查,整流二极管击穿是由于 DC /DC 模块瞬时启动重载使模块内部功率调节时产生个别幅度较高的电压毛刺; 并且两路陀螺组合同时启动时,电源母线负载较大致使输入端的电压波动较大; 加之整流二极管能量耐受力不够,三方面的原因共同造成 DC /DC 模块整流二极管被电压击穿,从而引发 DC /DC 模块失效。 |
It was shown by fault tree and experiments that three reasons wereresponsible for the breakdown of the rectifier diode. Firstly,with the startup heavy load of the DC /DCmodule,there were some high-amplitude voltage burrs resulted from internal power regulation. Secondly,when the two gyros were combined to start at the same time,heavy loads of the power bus increased thefluctuation of the input voltage. Finally,the permissible power of the rectifier diode was not enough. Thethree reasons caused the breakdown of the rectifier diode,resulting in the failure of the DC /DC module. |
