要約(英語): This paper discusses the electric energy consumption of a permanent magnet synchronous motor (PMSM) drive system applied to a two-level inverter or a three-level inverter. The calculation method of energy consumption based on an efficiency map is proposed. First, the energy consumption of the motor drive system is measured. When the three-level inverter is applied, the energy consumption decreases by 3.67% compared with the two-level inverter. Next, it is confirmed that the error ratio between the calculation result and the measurement result is 4.40%. In addition, the energy consumption of the PMSM drive system for hybrid electric vehicles is calculated by the proposed method. Thus, it is clarified that when the three-level inverter is employed, the energy consumption decrease ratio compared with the two-level inverter in the low-speed and low-torque region is higher than that in the other region.
