Power Sharing Control Strategy of High-Frequency Chain Matrix Converter Parallel System Based on Adaptive Virtual Impedance

Abstract In the high frequency link matrix converter parallel system, impedance parameters on each line are unequal so that output power of is not equal. To solve this problem, reason why cannot be divided equally under droop control strategy analyzed, and a sharing based adaptive virtual proposed. This introduces in voltage-current dual-loop system with control, uses converter’s information factor to adaptively adjust amplitude phase impedance, different branches have same equivalent compensate The voltage drop while adding fine-tuning compensation link, as realize load sharing. Simulation results show proposed can effectively improve accuracy ensure stability amplitude.
