摘要 开关模型的物理概念明确,在其基础上分析了三相电压型逆变器的每相桥臂开关模型,进而建立了变换器带阻性负载时的模型,然后用派克变换对其进行线性变换,从而得到了开关在通态时的线性模型。最后用Matlab进行了仿真。 The physical concept of switch model is clear, based on which, one-phase-leg model of three-phase voltage source PWM inverter is analyzed. Further, a three-phase voltage source PWM inverter model with resistive load is built. The Park transformation is applied to this model for obtaining linear changes and thus a linear model is achieved. Matlab is used in the simulation analysis.
