地波雷达是从事海洋环境研究以及电波传播相关理论探索的关键设备,设备安装和使用条件恶劣,并且处于连续运行状态,如何通过良好的维护来保证地波雷达的可靠运行,尤其是雷达的大功率发射设备,已成为使用和保障部门的重要课题。文中主要介绍了一种地波雷达微波管发射机的电源系统的组成,重点分析了阳极高压开关电源的电路原理,提出了变形脉宽调制控制的概念。经过仿真和稳态工作波形分解,得出了该电源高可靠性和高效率的结论,给出了电源的主要工作电流、电压波形,希望为设备的使用和维护提供参考。
Ground wave radar is engaged in marine environment research and radio wave propagation related theories to explore the key equipment, equipment installation and use conditions are harsh, and in continuous operation, how to ensure the reliable operation of ground wave radar through good maintenance, especially the large radar Power transmission equipment, has become an important issue for the use and security departments. This paper mainly introduces the composition of the power system of a ground wave radar microwave tube transmitter, emphatically analyzes the circuit principle of the anode high voltage switching power supply and puts forward the concept of deformation pulse width modulation control. Through the simulation and steady state waveform decomposition, the conclusion of the high reliability and high efficiency of the power supply is obtained. The main operating current and voltage waveform of the power supply are given. It is hoped that the reference will be provided for the use and maintenance of the equipment.
