电源是仪器的一个组成部份,如果一台仪器的电源工作不理想,同样要影响这台仪器的使用效果,因此,必须对仪器的电源部份给以应有的重视。根据我们工作情况来看,海洋调查、科研用电子仪器电源主要有两类,即低压直流电源,逆变源或直流电压变换器。低压直流电源主要用于仪器电路部分。逆变源或直流电压变换器主要用在没有交流电(有直流电)的情况下给交流负载或高压直流负载配套。现将这两类电源的工作原理及一些实用电路作一初步介绍,供海洋调查队、船队,台站有关同志参考。
The power supply is an integral part of the instrument. If the power supply of an instrument does not work well, it also affects the performance of the instrument. Therefore, the power supply part of the instrument must be given due attention. According to our work situation, there are two main types of power supply for marine research and scientific research: low-voltage DC power supply, inverter source or DC voltage converter. Low-voltage DC power supply is mainly used for the instrument circuit part. Inverter source or DC voltage converter is mainly used in the absence of AC (direct current) to the AC load or high-voltage DC load supporting. Now the working principle of these two types of power supply and some practical circuits for a preliminary introduction for the marine investigation team, fleet, station gay reference.
