摘要
电力通信电源供电系统需要满足高动态与稳态特性的要求,以保证负载大幅波动时,电能输出稳定,从而保证通信系统的正常工作,避免引起电力系统通信事故。研究V^2C控制方法,通过建立小信号数学模型,分析变换器输出特性,进而设计V^2C控制器,通过软件仿真、硬件实验,对该控制方法进行验证。结果表明,V^2C控制方法保证变换器良好动态与稳态输出特性,提高了变换器的响应速度与稳态精度,改善了系统稳定性,优化输出特性。
The communication power supply need to meet the requirements of high dynamic and steady state, so as to ensure the stability when disturbed.VZC control method is studied by analyzing the small signal model.Then the V2C control method is put forward to improve dynamic response and stability of system when disturbed.Finally,the controller is verified by simulation and experiments.The results show that the V2C control method improves the dynamic response and the accuracy of the converter in the full range of load, while the stability is better.
