摘要
本文介绍了三相电压型PWM整流器相位-幅值控制的基本原理,对系统的控制策略进行了研究。在理论分析的基础上,建立了系统的MATLAB仿真模型。利用此模型得到了系统各点的波形,实现了交流侧功率因数为1,直流输出电压稳定的控制目的。同时,提出了利用直流电压微分负反馈环节提高系统的抗扰性能。利用TMS320LF2407DSP进行了系统实验,仿真和实验验证了控制策略的正确性和可靠性。
The paper presents the basic principle of Phase-Amplitude control, researches the system control strategy, On the base of theory analysis, the system MATLAB simulation model is constituted. By using the model gets the system diagrams of every point. After analysis the diagram, the AC side Power Factor is 1 and the output DC Voltage is steady, At the same time, in order to im- prove the system performance of resisting disturbance, DC voltage differential negative feedback is advanced. By use of TMS320LF2407DSP, system experiment is done. The simulation and experiment results confirm the reliability and validity of the control strategy.
