三电平T型多相逆变器直流母线电容电压平衡研究

This article illustrates an algorithm to balance the voltages across the dc-link capacitors of a three-level multiphase inverter feeding a star-connected load with an odd number of phases. The proposed strategy keeps the dc-link capacitors balanced in any operating condition and minimizes the low-frequency voltage oscillations, even during open-phase faults and with non-sinusoidal output currents....
