This paper suggested a circulating current control strategy dedicated for paralleled multilevel t-type inverters. The suggested circulating current control strategy consist in integrating into the three-level space-vector pulse width modulation a control variable allowing the adjustment of small vectors duty cycles. The method is easy to implement for modular design, and can effectively eliminate the circulating current even though, the inverters have an asymmetry in hardware or control parameters. The effectiveness of the proposed circulating current control is validated under different operating conditions through Processes-in-the Loop simulation (PIL) using TMS320F28335 DSP board.
