A Half-bridge Power Quality Conditioner Based on One Cycle Control

In this paper, the half-bridge power quality conditioner (PQC) is analyzed. On this condition, the half-bridge power quality conditioner based on one cycle control theory is proposed and is also analyzed. The analysis results indicate the PQC based on one cycle control theory can effectively suppress and isolate voltage-based distortions. At the same time, the PQC can eliminate the current harmonic and compensate reactive current. And the analysis results also shows that not only the control precision is improved,but also the control circuit is simple. The simulation results are given which verify the correctness and effectiveness of the proposed method.
