| 摘 要： | 四桥臂三相逆变器的结构,其三相负载可以是平衡的或不平衡的、线性的或非线性的.由于第4桥臂的加入,其控制变得更加复杂.针对国内外四桥臂三相逆变器各种控制方法的优缺点,消除四桥臂三相逆变器在带不平衡和非线性负载时的三相输出电压不平衡,讨论使用对称分量法对其进行控制.仿真和样机实验结果表明,这种思路是可行的.

| Abstract: | The structure of four-leg three-phase inverter is introduced,whose load can be an arbitrary load,unbalanced or balanced load and linear or nonlinear load.With an additional forth leg,the system control becomes very complex.The advantages and disadvantages of various controlling methods for four-leg three-phase inverter are introduced in the domestic and international field.In order to eliminate the unbalance of three-phase output voltage of four-leg three-phase inverter with unbalance and nonlinear load,the... |
