His policy is to do his best for both of research and playing. If we have problems about research, he always accepts to discuss technical issues with us. He also participates in futsal tournaments that is planed by the laboratory member.

Research Content

Recently, Power Electronics is an important key to problems of global warming and nuclear power generation. Power Electronics is technique to utilize electrical energy efficiently. It is applied for wide field such as industrial machines, electrical vehicles and home appliances. In Itoh laboratory, we are doing research about power converter, motor drive, wireless power transmission, smart grid for renewable energy, energy storage and so on. Our laboratory is leading technique of evolving Power Electronics.

Matrix converter(I made this one from scratch.)

A Day in the Lab

AM : After morning assembly, I do simulation and theoretical analysis to contrive a novel method.
Noon break : we often eat lunch with laboratory's members.
PM : I made a main circuit and a controller to do experiments. Some members write paper for upcoming conferences until late. Others continue to do experiments.
It's important to take enough rest in the evening so as to be active.

Our Laboratory has many labmate at the toughest time.
