随着微电子技术和电子电力技术的不断发展，高频开关稳压电源正以体积小、效率高等优点而广泛应用于各种军用、民用仪器仪表、控制设备产品中。激光电源作为一种特殊开关电源，和普通开关电源的区别是负载伏安特性完全不同，本文主要介绍了一种基于UC3825芯片的重复频率激光电源的工作原理，它采用半桥式变换电路，利用UC3825进行电流型调制，用IR2110双通道驱动芯片驱动场效应管，采用单片机AT89C51组成的控制电路对脉冲激光氙灯进行重复频率充放电控制，最终成功实现了一种基于UC3825芯片的重复频率激光电源的研制。
隨著微電子技術和電子電力技術的不斷髮展，高頻開關穩壓電源正以體積小、效率高等優點而廣汎應用于各種軍用、民用儀器儀錶、控製設備產品中。激光電源作為一種特殊開關電源，和普通開關電源的區彆是負載伏安特性完全不同，本文主要介紹瞭一種基于UC3825芯片的重複頻率激光電源的工作原理，它採用半橋式變換電路，利用UC3825進行電流型調製，用IR2110雙通道驅動芯片驅動場效應管，採用單片機AT89C51組成的控製電路對脈遲激光氙燈進行重複頻率充放電控製，最終成功實現瞭一種基于UC3825芯片的重複頻率激光電源的研製。

With microelectronic technology and power electronic technology development, high frequency switching power supply with small volume, high efficiency, etc. are widely used in various military, civilian insmunents, control equipment products. Laser power as a kind of special switching power supply, switching power supply and the common difference is load volt - ampere characteristics are quite different, this paper mainly introduces one kind based on the UC3825 chip repetition frequency laser power supply works, which utilizes half- bridge converter circuit, using UC3825 electric cun'ent modulation, using IR2110 dual channel driving chip driving FET, the single chip microcomputer AT89C.51 control circuit composed of a pulse laser repetitive frequency of xenon lamp charging and discharging control, ultimately the suecesafitl implementation of the one kind based on the UC3825 chip repetition frequency laser power supply.
