Professor / ITOH Jun-ichi
Prof. Itoh loves power electronics and sake. He values close communication with students. When students face difficulties in their research, he is always open to discussion and provides precise advice. He also actively participates in laboratory events, enjoying skiing and cycling with students.

Research Content

In our laboratory, we focus on power electronics to address global warming and energy issues. Power electronics enables the efficient use of electrical energy. It is widely applied in industrial equipment, electric vehicles, and home appliances. The Itoh laboratory covers core technologies in power electronics, including power converters, motor drives, and wireless power transfer. We actively participate in domestic and international conferences to present our research results. The Itoh laboratory is one of the most active laboratories in the global power electronics field.

A Day in the Lab

The motto of the Itoh laboratory is to give full effort to both research and play. Each student has an individual research theme. Students experience the full research process from simulation to experiments. The Itoh laboratory has many experimental facilities, such as power supplies, electronic loads, power meters, and BH analyzers. Many doctoral students are members of the laboratory, so students can have active discussions about research. In addition, events such as beach barbecues and ski trips help students build strong relationships with staff members and other students.
