近年来,许多报刊报道了场效应治疗仪的神奇疗效,但介绍其电路结构与制作的文章尚不多见。实际上,构造极其简单,容易自制.经对某治疗仪进行解剖,发现其电路如图1所示。工作原理如下:交流220V市电经电源开关,变压器初级绕组和熔丝构成回路,在次级绕组的抽头中感应出21V、27V和36V的电压,经转换开关选调好再供给场效应带。
In recent years, many newspapers and magazines reported the magical effect of field-effect therapeutic apparatus, but the article introducing its circuit structure and making is still rare. In fact, the structure is extremely simple and easy to make.Analyzing the appearance of a therapeutic apparatus and its circuit is shown in Fig.1. The working principle is as follows: AC 220V electricity through the power switch, the transformer primary winding and fuse loop, the secondary windings induced in the tap 21V, 27V and 36V voltage, the switch to select and then supply the field effect zone.
