摘要:
针对四桥臂逆变器,提出了基于三相综合补偿的四桥臂控制方法。分析了四个桥臂在逆变过程中的作用,形成了三相综合补偿策略。该补偿策略用第四桥臂补偿输出不平衡因素,形成第四桥臂和各相桥臂综合补偿相电压的模式,发挥出四桥臂结构的优势,在阻性(或感性)不平衡负载条件下,增强了控制能力。基于三相综合补偿策略,文中针对电感电流为正弦波的特征,采用积分算法逼近电感电压,构造闭环控制结构,并给出四个桥臂的控制方法。该控制方法避免了微分算法引入的高频干扰和通用滤波算法引入的相位偏移,确保了输出电压收敛于理想波形。仿真结果验证了四桥臂综合控制方法的有效性。
Abstract:
A control scheme based on three-phase integrated compensation is proposed for four-leg inverter.The functions of four legs are analyzed in the power conversion process,and the integrated compensation strategy for three-phase voltages is formed.In the proposed compensation strategy,unbalanced factor is compensated by the fourth leg,and phase voltages are synthetically compensated by the fourth leg and every phase legs,so that the advantage of the four-leg topology is exerted and the control ability is increa...
