中文摘要:在第四代移动通信系统中,调制射频放大器输入信号包络幅值变化较大,带宽比较高,采用恒压给RF功率放大器供电,损耗巨大。而基于ARM的通信电源允许电源电压随输入信号包络的变化而变化,实现了放大器功率管电压相对较小的下降,从而提高了系统效率。提出了一种基于ARM的通信电源的电流最优控制算法,使开关电源的工作频率恒定,该算法通过引入输出电压前馈支路,进一步减少了组合辅助电源,提高了系统的效率,并进行了实验验证。

Optimal Control Algorithm of Communication Power Supply Based ARM
Abstract:In the 4G mobile communication system,the amplitude of the input signal envelope of the RF amplifier is variable,the bandwidth is higher,and the constant voltage is used to power the RF power amplifier,the loss will be huge. ARM communication power allows the supply voltage change with the change of the input signal envelope,realizing relatively small drop in the amplifier power tube voltage,thereby improving the system efficiency.,This paper presents an optimal control algorithm of the ARM communication power supply based on the fusion of composite membership function is put forward in this paper,which makes the work frequency of the switching power supply constant. The control method is improved,and the efficiency of the system is improved by introducing the output voltage feed forward branch to further reducing the combined subordinate power supply. and experimental verification is carried out.
