- Abstract
- This paper proposes a winding changeover circuit that can change the characteristics of the motor in order to increase the practical driving efficiency of electric vehicles. The proposed circuit is constructed using a Thyristor switch device, and has an advantage that the overall system loss is relatively low. The proposed circuit control scheme was introduced, and the advantages and disadvantages of the existing developed circuit were compared. And the proposed circuit was verified with 80kW PMSM and inverter.
