基于三相四桥臂逆变器消除传导共模电压的三维矢量脉宽调制技术研究
A study of three-dimensional vector pulse width modulation technique based on three-phase four-leg inverter with conducted common mode voltage elimination
摘要
Abstract
In order to reduces the reliance on large common mode chokes for 3-phase 4-wire inverter power systems,three-phase four-leg inverter is taken as the research object.A 3-dimensional-zero common mode voltage vector pulse width modulation(3D-ZCPWM)is proposed by combining 3-dimensional-space vector pulse width modulation(3D-SVPWM)with conducted common mode voltage elimination method(CMVEM),which eliminates the conducted common mode voltage while guaranteeing the freedom degree of zero-sequence component control.The lack of freedom degree of the zero-sequence component control in the existing CMVEM is supplemented.The simulation and experiment results show that the strategy proposed in this paper has a strong ability to eliminate the common mode voltage and the three-phase four-leg inverter based on this strategy has the ability to withstand unbalanced loads and maintain stable output voltage.关键词
