CPU-50/128-333-4-2 FORCE模塊發熱嚴峻
電源模塊在電壓變換進程中有能量損耗，發生熱能導致模塊發熱，下降電源的變換功率，影響電源模塊正常工作，但什麼情況下會形成電源模塊發熱較嚴峻呢?
l運用的是線性電源模塊;
l負載過流;
l負載太小：負載功率小於模塊電源輸出功率的10%，都會有可能會導致模塊發熱(功率太低);
l環境溫度過高或散熱不良。
熱成像儀觀測下的發熱電源模塊如圖2所示：
解決方法：
1)運用線性電源時要加散熱片;
2)進步電源模塊的負載，保證不小於10%的額定負載;
3)下降環境溫度，堅持散熱傑出。
四、輸出噪聲較大
噪聲是衡量電源模塊好壞的一大要害目標，在運用電路中，模塊的規劃布局等也會影響輸出噪聲，哪些因素對輸出噪聲有較大影響呢?
l電源模塊與主電路噪聲靈敏元件間隔過近;
l主電路噪聲靈敏元件的電源輸入端處未接去耦電容;
l多路體係中各單路輸出的電源模塊之間發生差頻攪擾;
l地線處理不合理。
ZDS2024示波器測驗有較大噪聲攪擾問題的電源模塊，如圖3所示：
解決方法：
1)將電源模塊盡可能遠離主電路噪聲靈敏元件或模塊與主電路噪聲靈敏元件進行隔離;
2)主電路噪聲靈敏元件(如：A/D、D/A或MCU等)的電源輸入端處接0.1μF去耦電容;
3)運用一個多路輸出的電源模塊替代多個單路輸出模塊差頻攪擾;
4)選用遠端一點接地、減小地線環路面積。
