PURPOSE:To reduce the equivalent disturbing current to minimum by selecting the reactance ratio of the respective coils to the entire reactance to 2-3. CONSTITUTION:A primary coil 3, a phase controlling coil 4 and noncontrolling coils 5, 6, 7 are provided on a core 2 of a transformer 1 for a vehicle, and the ratio k= N.Xi/XT, where N represents the number of division, is set to 2-3 when the reactance of the respective coils with respect to the entire reactance XT is set at Xi, thereby reducing the equivalent disturbing current to minimum. |
