一、前言人们日益重视对海洋的开发,为了进行某种试验工作,潜艇必须给地面上的观测站一定的光信号,目前大都是采用大功率脉冲灯来获得,其优点是具有极强的瞬时功率,有极强瞬时光输出。脉冲灯需要直流高压供电,而在潜艇上由于某种需要,不能安装交流发电机,只有220V直流电源的情况下,就必须采用一种把220V直流电变换成交流电的变换器,然后经过 First, the foreword People pay increasing attention to the development of the oceans, in order to carry on some kind of test work, the submarine must give certain optical signals to the observatory on the ground, at present mostly adopt the high-power pulse lamp to obtain, its merit is that has extremely strong instantaneous Power, there is a very strong instantaneous light output. Pulsed lamps need DC high voltage power supply, and in the submarine due to some needs, can not install the alternator, only 220V DC power supply, you must use a 220V DC to AC converter, and then through
