摘要
在VIENNA整流器平均电流模式控制中,为了解决电流过零交越失真的问题,提出了增加占空比前馈的改进型控制方法。在详细介绍VIENNA整流器数字控制策略的基础上,分析了环路控制方案。通过Matlab仿真,验证了此方法的可行性。以TMS320F28035作为控制核心,构建了一台10 kW的VIENNA整流器实验样机,实验结果表明,该改进型的控制方法改善了输入电流波形,提高了系统性能。
In order to solve the current zero crossing distortion problem in VIENNA rectifier average current mode control,an improved control method based on duty-ratio-feedforward is proposed.In detail,on the basis of digital control strategy of VIENNA rectifier, control proposal of the loop is analyzed.The feasibility of this method is initially verified by Matlab simulation.A 10 kW converter with TMS320F28035 as core controller is realized.The experimental results show that the improved average current mode control can improve the input current waveform and the per- formance of the system.
