Converter applications, can be divided into two categories: one is used for transmission speed, and the other is a variety of stationary power (static power is not the time being).
变频器应用，可分为两大类：一种是用于传动调速，另一种是各种静止电源(静止电源暂且不讲)。
Several schemes for the static converter with low input voltage are analyzed. All these schemes are difficult to be used in heavy power application.
分析了低压静止变流器的几种技术方案，这些方案均难以做到大功率应用。
