本文把許多熟知的磁心取数开关化成单一的分析模型。在这基础上又导出了许多新的开关。文中指出了模型的各个参数之間的联系,使設計者在一定范圍内可以选擇驅动器的数目,均分員載系数,每个开关磁心的线圈匝数以及最大噪音磁势的幅度。还发展了节省开关中使用的驅动器数目的几种方法,討論了一些特殊的取数开关。均分負载的零噪音开关是最近流行起来的一类重要的取数开关。文中对这些开关作了比較,并且証明了一个基本定理,指出这类开关的輸出数目不能比輸入数目更多。最后,发展与分析了几类新的均分負載零噪音开关;特别是,所发展的一些开关在选擇均分負载系数时比以前的更为灵活。
In this paper, many well-known magnetic core access switches into a single analysis model. On this basis, many new switches have been exported. The paper points out the relationship between the various parameters of the model, so that the designer can select the number of drivers, the average load factor, the number of turns of each switching core and the magnitude of the maximum noise magnetic susceptibility within a certain range. Several approaches have also been developed to conserve the number of drives used in the switch and some special take-off switches have been discussed. Zero-noise load sharing of the load is an important type of access switch recently. The paper compares these switches and proves a basic theorem that the output of such a switch can not be greater than the number of inputs. Finally, several new types of load sharing zero-noise switches were developed and analyzed; in particular, some of the switches developed were more flexible than before in selecting a load sharing factor.
