This paper introduces a resistor-source control strategy for T-type three-level converter. The converter can be seen as a resistor source and the grid synchronization is realized by virtual resistor. In αβ frame, the virtual resistor is constructed in the form of a second-order transfer function. The power transmission is realized by adjusting virtual resistor at the fundamental frequency, and the virtual resistor at other frequency is used to ensure the system stability. Besides, the introduced resistor-source method does not need grid voltage sensors. The introduced resistor-source control strategy is simple and easy to implement. Finally, the effectiveness of the introduced method is verified by simulation results.
