基于O-Z源阻抗网络的中点钳位三电平逆变器性能分析与拓扑研究

To address the issues of conventional Z-source inverter (ZSI), insufficient boosting capacity, high capacitor voltage stress and large starting impulse current, a novel NPC three-level inverter (O-ZSI) topology is proposed based on the O-type Z-source impedance network. First, a steady-state analysis of the new O-Z-source inverter topology structure is conducted, deriving expressions for the dc-li...
