摘要
Abstract
An advanced control strategy for cascade H-bridge inverter was proposed to track grid current in case of grid distortion. In the case of grid distortion,a proportional integral resonance control was proposed. The fundamental current was tracked by the proportional integral controller. At the same time,the resonant controller could realize the AC component of the grid distortion and control the current accurately. In view of the power imbalance of H-bridge inverter,the method of changing zero-sequence component was proposed to realize power balance control. The simulation and experiment show that the H-bridge inverter can be prepared to control the grid current under the condition of grid distortion.关键词
