摘要：

This study proposes a dedicated modulation scheme for a bidirectional quasi-Z-source (qZS) modular multi-level converter. The operation principle and a suitable pulse-width modulation method are proposed. The relation between the modulation index and shoot-through duty ratio is derived. A formula for calculating the required value of qZS capacitance is given. The simulation results presented in the study validate the operation and the performance of the proposed topology.
