摘要
采用坐标变换的数学手段,推导出了三相电压型PWM整流器(简称VSR)在两相同步旋转坐标(即dq坐标)下的数学模型,实现了有功和无功的解耦,使三相坐标系中的交流量变成了dq坐标系中的直流量,为实现高性能的控制提供了条件。并得出了整流器运行在单位功率因数状态下的dq矢量等效电路。
Based on coordinates transform,the mathmatic model of the three pulse VSR in two - phase synchronization coordinates(d-q coordinates) is reason out, active and reactive power can be decoupled, and turn the AC variable of three pulse coordinates to the DC variable of d - q coordinates, provide the condition to realize the high capability . The dq vector equivalent circuit of rectifer which running in the unity power facto was gotten.
