一种在宽功率因数下运行五电平混合钳位逆变器并增强中点电压平衡能力的调制策略

Clamped multilevel inverters suffer significantly from neutral point (NP) voltage unbalancing in low power factor applications, which will lead to severe device overvoltage problems and affect its output performance. The five-level hybrid clamped (HC) inverter is a state-of-the-art topology with additional redundant switching states, which makes it possible to suppress the NP low-frequency voltage...
