本文给出了实用的无变压器固体激光电源方案。在以倍压为基础的充电主回路实验基础上,得出了倍压充电速度公式,此式在较大范围内和实验结果基本相符。给出了几种不同的倍压线路。 This paper presents a practical transformerless solid-state laser power scheme. Based on the experiment of charging main circuit based on voltage doubling, the formula of voltage doubling charging speed is obtained, which is in good agreement with the experimental results in a wide range. Several different voltage doubling lines are given.
