The DQZ transformation uses the Clarke transform to convert ABC-referenced vectors into two differential-mode components (i.e., X and Y) and one common-mode component (i.e., Z) and then applies the Park transform to rotate the reference frame about the Z axis at some given angle. 2008-9-28 SUN Dan College of Electrical Engineering, Zhejiang University 4 Introduction A change of variables is often used to reduce the complexity of these differential equations.
