摘要
雷达中含有大量的电力电子元件,供电系统结构复杂。文中以现有雷达负载模型为基础,考虑了雷达负载中的降压部分,提出一种将相控阵雷达结构简化为整流降压变换器、直流开关、脉冲负载三个模块的新型脉冲负载结构及模拟方法;推导了新型脉冲负载的数学模型;通过仿真分析了脉冲负载参数占空比D、峰值功率PL、周期TS变化对电网运行规律的影响;通过搭建实验平台验证了仿真分析的正确性。
The radar has abundant electronic components and a complicated electricity supply system. In this essay,reduction voltage component has been considered in the foundation of current radar load model and a new pulse load,simulation method and a pulse load mathematic model have been put forward based on rectified buck converter,direct current switch,pulse load simplified by phased array radar. The effects of pulse load parameter duty cycle D,peak power PLand periodical TSchanges has been analysed through simulation. The validity of simulation are verified by establishing experiment platform.
