摘要：
Through the analysis of the switching state of the neutral point clamped (NPC) three-level interleaved parallel H-bridge inverter, 31 kinds of effective switching vectors are obtained. Based on the analysis of the effect of effective switching vector on the neutral point potential of capacitor and the parallel current of bridge arm, a single-phase space vector pulse width modulation (SVPWM) method using redundant vector to balance the neutral point potential of capacitor and the parallel current of bridge arm is proposed, and a simulation model is built under the MATLAB / Simulink platform for simulation. The simulation results confirm that the validity of the proposed method.
