Design and analysis of DVR system for strong unbalanced voltage suppression

For three-phase instantaneous voltage dip amplitude difference problem, a method using each independent structure of H full bridge converter circuit. Introduces the main circuit topology of the method, and the principle of the DVR system, the control strategy and the corresponding simulation results; through the experimental results show that the method is effective to solve the problem of strong unbalanced voltage suppression, and also pointed out its advantages and disadvantages.
