摘要
此处从H桥级联型逆变器拓扑结构出发,推导出了H桥级联型逆变器电压输出实质是其各H桥左桥臂与右桥臂形成的两电平逆变器组输出电压之差,从而利用相移原理与空间矢量脉宽调制(SVPWM)推导出了适合于H桥级联型逆变器的相移SVPWM。通过十三电平H桥级联型逆变器驱动系统的实验验证了该方法的有效性。
Based on the topology structure of H-bridge cascaded multi-level inverter（HBCMI）, the output voltage of HB- CMI is deduced which is the difference value between two-level inverter group＇s output voltage formed by left bridge arms of all H-bridge and two level inverter group＇s output voltage formed by right bridge arms of all H-bridge.A suitable modulation of phase-shifted space vector pulse width modulation （SVPWM） is introduced for HBCMI by using of phase-shiftd principle and SVPWM.To verify the algorithm, a thirteen-level cascaded H-bridge inverter drive sys- tem is constructed and simulated, the simulation and experimental results validate the validity of this algorithm.
