電源轉換器(power converter devices, PCD)衝擊與振動

最近因為選用Power supply(PSU) 的問題，參閱了底下文件，也包含IPC- 9592 文件中指出
but not limited to the computer and telecommunications industries.小弟的產業別剛好屬於telecom 這一塊。也沒什麼大礙。

重點想請教老師及各位前輩除了底下的文件,最後一份的第六章有提到減額因子的計算,以參考選用

6.Loading Criteria For Efficiency Testing
6.1.1.1 Method of Proportional Allocation Based on Overall Power Supply Rated Dc
Output Current With No Sub-group Ratings
The manufacturer has provided rated dc output current limits for each bus and an overall rated dc
output power for the power supply. The approach for loading criteria is as follows:
Assume a power supply with four output voltage busses. A sample output specification of this
power supply is shown in Table 6-1.

不知以系統而言, PSU 的選用Derating 還有那些文件可參考? 或是其他建議! 感謝!
