具有任意直流母线电压分布的双两电平逆变器混合过调制策略

This article introduces an innovative overmodulation strategy for a dual two-level inverter topology featuring galvanically isolated dc-links and accommodating arbitrary distribution of dc-bus voltages. In such a configuration, the uneven distribution of dc voltages gives rise to 12 additional fundamental voltage vectors compared with the conventional two-level inverter, effectively enabling the t...
