目前,空间飞行器中电子设备的能源,主要是由蓄电池来提供,而各种电子设备所要求的电压高低和电流的大小是通过 DC—DC 变换器来实现,这是一个很有效的途经,特别是对多组输出而言尤其是这样。这些电子设备所要求的电源大体都有一些共同的特点,主要是:1.稳压.2.效率高,3.直流输出端的波纹峰——峰值要小,4.体积小,5.重量轻,6.在高温(+85℃)下仍能正常的工作,7.工作可靠。
At present, the energy of electronic equipment in spacecraft is mainly provided by the battery. The voltage level and the current required by various electronic devices are realized by the DC-DC converter, which is a very effective way. In particular, This is especially true for multi-group outputs. The power required by these electronic devices generally have some common features, mainly: 1. Regulator 2. High efficiency, 3. DC peak ripple output - to small, 4. Small size, 5. Light weight , 6 at high temperature (+85 ℃) can still work properly, 7. reliable work.
