【Abstract】 For the main transformer with mutual inductance among its traction windings in AC drive (Electric) Multiple Unit, the working state of 4-quadrant converter (4QC) is studied. According to the analysis of AC vector diagram, the effect of the mutual inductance among the traction windings on the control (performance) of the 4QC is discussed. Based on the analysis of the stability of the 4QC state equation, the value of mutual inductance should be smaller than that of leakage inductance of the traction windings. The control equation can be derived by discretizing the 4QC state equation and be practically applied in engineering. (Computer) simulation is conducted to determine the value of the mutual inductance and to verify the feasibility of the proposed control method.更多还原
