行波管工作电源的设计

Design of a TWT Power Supply

发射机是电子干扰系统的重要组成部分 ,它的核心部件是行波管放大器。发射机的所有电路基本上都是围绕着如何给行波管的各电极提供正确稳定的工作电压及使行波管正常工作的各种保护和控制功能而设计的。简要介绍了行波管电源设计中的一些问题、方案选取以及具体电路的实现 ,重点分析了主高压电源所采用的零电压谐振全桥变换器的工作原理。

The transmitter is an important component of the electronic jamming system, TWTA is its heart. All circuits of the transmitter are basically designed to offer the proper, steady voltage for the electrodes of TWT and various protective, control functions for its smooth operation. Some questions, selecting the project and realizing idiographic circuits are introduced, the operational principle of a ZVS resonant fullbridge converter is mostly analyzed which is adopted by the main highvoltage power supply.
