摘要
介绍了通过 Clarke和 Park变换 ,可将静止坐标系中三相交流电流 ia、ib和 ic变换成静止坐标系中的二相交流电流 iα、iβ,再将 iα、iβ 变换成与转子磁链同步旋转的坐标系中的二相直流电流 isb、isq,给出 Clarke和Park变换的数学表达式 ,在数据信号处理器 ( DSP) TMS3 2 0 C2 4 0上实现了该种变换。
Clarke and Park transforms is the main part of vector control on inverter. Through the use of Clarke and Park transforms, three\|phase AC current i\-a i\-b and i\-c can be used to calculate current in the two\|phase orthogonal stator axis:i\-α and i\-β. These two currents in the fixed coordinate stator phase are transformed to the two\|phase DC i\-\{sd\} and i\-\{sq\} currents components in the d,q frame. This paper gives out the mathematical formula of Clarke and Park transforms and describe Clarke and Park implementation on the DSP TMS320C240.
