| Abstract |
The dual three-phase permanent magnet synchronous motor drive system consist of dual three-phase inverter and dual three-phase stator winding set in motor. The dual drive-mode that utilizes dual stator winding set and dual three-phase inverter is commonly used for general operation. However, in order to improve the total efficiency of the drive system, it is also necessary to consider the efficiency of a single drive mode such as a conventional three-phase drive. In this paper, the high efficiency drive strategy of dual three-phase permanent magnet synchronous motor is proposed to utilize the highest efficiency point in each drive mode. Based on the analysis about efficiency for each drive-mode, the drive-mode changeover is proposed. The experimental results validate the proposed high efficiency drive strategy. |
