Outline of Final Research Achievements

Generally, the three-phase AC/DC converters are used for a lot of applications, such as the Shinkansen trains, hybrid electric vehicles (HEV), power conditioner systems (PCS), and so on. Therefore, this research clarifies the optimum pulse width modulation (PWM) scheme for the AC/DC converters. In this research, two facts are clarified as follows; the references-shifted two-phase PWM scheme is suitable for the motor-drive systems without the harmonic filter, and a pulse-injected two-phase PWM scheme is suitable for the PCSs and the motor-drive systems with the harmonic filter.
