本文讨论了在高速操作中采用磁心均分负载开关驱动一个双向二极管矩阵的可能性。为了便于分析,将每个开关磁心看作是一个脉冲变压器。达脉冲变压器的必要参数是利用波源阻抗、负载阻抗及脉冲的要求而计算出来的。给出了脉冲变压器及一个由3×3个二极管及作为负载的磁心元件构成的矩阵(用三个磁心均分负载开关驱动的)的实验结果。得出的结论是:采用四个均分负载开关来驱动一个重复频率为十兆赫的双向二极管矩阵是可能的;采用两个均分负载开关可获得五兆赫的操作。
This article discusses the possibility of using a core-sharing load switch to drive a bidirectional diode matrix in high-speed operation. For ease of analysis, consider each switch core as a pulse transformer. The necessary parameters for a pulse transformer are calculated using the wave source impedance, load impedance, and pulse requirements. The experimental results of a pulse transformer and a matrix consisting of 3 × 3 diodes and a magnetic core element as a load (driven by three magnetic core load sharing switches) are given. The conclusion to be drawn is that it is possible to drive a bi-directional diode matrix with a repetition rate of ten megahertz using four load sharing switches; five megahertz operation is achieved with two load sharing switches.
