分析了三电平电压空间矢量调制基本原理,深入研究了影响三电平逆变器中点电压平衡的主要因素,由此提出一种控制箝位二极管电压型三电平逆变器中点电压平衡的电压空间矢量算法理论分析和仿真实验结果表明。
The basic principle of three-level voltage space vector PWM is analvzed The main factor which in(?)uenccs nen-tral-point voltage balance of three-level inverter is deeply stndied Hence a new voltage space vector control algorithin of neutral-point voltage balance in three-level (?)ode-(?)amped voltage source inverfer is proposed. The simulation experimental results are given to verify the reliability of the proposed control scheme for balancing neutral-point voltage in three-level inverter.
