摘要

理论分析了三相四桥臂逆变器现有电流调节方案存在的局限性

提出可变空间矢量控制策略

采用简便的方法解决了在对称负载情况下的中线电流问题

在两种情况下的仿真结果验证了其正确性及可行性

该方案可广泛应用于三相、四线有源电力滤波器等电力电子系统中。

Abstract

The limitations

which exist in current regulation schemes of three-phase four-leg inverters

are analyzed.Adaptive SVPWM control strategy is presented

which solves the problem of the neutral line current in case of symmetrical load.Simulation results verify the validity of the presented control scheme.This scheme can be applied in electric electronic system extensively

such as active power filter.
