提高開關電源可靠性電路的研究

摘要：本文介紹了一種蓄電池充電開關電源，重點研究了其中軟啟動的設計，硬件消除開關機電路抖動干擾設計，輸入、輸出過流保護等提高開關電源可靠性的電路方案。通過設計了幾種保護電路，不僅很好地提高了蓄電池充電電源的可靠性，還在一定范圍內提高充電電源的效率。文章最后通過兩款可快速對24V/300Ah 蓄電池充電的開關電源樣機實驗進行了驗證。 敘詞：開關電源，開關機抖動，保護電路，可靠性，軟啟動 Abstract：This paper introduces a switching power supply for storage battery, focusing on the design of the soft-start, hardware circuit toeliminate the ON OFF jitter interference, input, output overcurrent protection. Its not only a good way to improve the reliability of thebattery charging power supply, but also a good way to improve the charging efficiency of the power within a certain range. Finally, it wasverified through prototype experiments of two switching power supplies for 24V/300Ah battery charging.
