摘　　要：变形镜驱动器正负电源加电或者断电不同步,导致其在加电瞬间或者断电瞬间,输出端会输出一个-38.0V和86.0V的冲击电压,这个冲击电压使得变形镜在未开始工作时就产生了较为严重的面形畸变,为此研制了基于微处理器的软启停直流电源,它输出两路按一定时序变化的输出电压作为后续两个继电器的控制端,再通过这两个继电器分别控制变形镜驱动器正、负电源的导断,从而使得变形镜驱动器的正负电源同时加载或者卸载;在硬件平台了进行了实验验证,结果表明,使用软启停直流电源后,变形镜驱动器加电瞬间或断电瞬间,其产生的脉冲电压的峰-峰不超过0.45V,远远小于未使用软启停直流电源前的冲击电压,满足了系统的设计要求。positive power and negative power asynchronism result in -38.0 V or 86.0 V impact pulse when deformer mirror driver pow er on or power off, this impact pulse will make deformer mirror deformed very well when deformer mirror is not in the working state. Aiming at avoiding this impact pulse influence on deformer mirror, make use of one micro controller system to output two different timing voltage, by using these two timing voltage to adjust solid state relay control endpoint, further control deformer mirror driver power on or power off, Ex periment results shows that deformer mirror driver power on impact pulse or power off impact pulse peak to peak value only is 0.45 V after using this device, very less than pulse maximum amplitude while not using this device, thus meet system design demand.
