| Research Abstract |
The essence of this research can be summarized into two points. One is that the ultra-high power density SAZZ chopper was realized with 100 kw/l with 50 kw output. The efficiency is about 99%. And the second point is that the energy saving rate of the adjustable motor drive with a chopper depends on the system configuration. In case of electric vehicle, the 3 % driving range extension was experimentally confirmed with JC08 driving mode test. And also if the weight of the chopper becomeslower and the dc voltage can be lower, the energy saving rate has possibility to become more than 10 %.
