双两电平逆变器系统的统一空间矢量脉宽调制

This letter proposes a unified space vector pulse width modulation (SVPWM) for a dual two-level inverter system with two isolated dc voltage sources. The gate pluses for the dual inverter are generated by the concept of one unified SVPWM in accordance with the voltage-second integral principle and the ratio of the two dc-link voltages can be an arbitrary positive value. This proposed technique als...
