摘　　要：设计作品箱式电位差计交流电源是一种运用两个变压器进行交流输出电源。设计作品利用变压器变压原理、二极管全波整流原理和三端稳压器件的工作原理。在设计上以交流电代替化学电池,它克服了原来该仪器使用成本高、安全性能差、环保性能低的缺点。The design device that using the alternating current of the box - type potentiometer utilizes two tranaformers to give out two kinds of AC output power source. It uses the transformer principle, the full - wave rectification principle involved by diodes, we also use a kind of constant voltage component which had three ends.It will replaces the chemical supply in our design. It has reduced its original high cost and is also helpful to the environmental protection.
