Associate Professor / Hitoshi HAGA
Associate professor Haga send out a music about power electoronics to the world, talks about "気合(Kiai)" in his lectures, and muscle trains when you visit him in the faculty room. He always responds to what the students want to do but he usually thinks more about beer than study. He often says, "Master the Power Lab with mind, body, and spirit!". Our teacher is the best!!

Research Content

As the name itself implies, skillful power conversion is the main topic. In particular, we research using index-terms such as "Application technology for power storage devices", "motor drive systems", "Reduction technology in power convertor". The research results contribute to the application of consumer electronics, automotive and various power source mainly through industry-academia collaboration. At the Haga-Laboratory, you can engage in power conversion technology research. We take into account the control methods, circuit design, simulations and experiments, and develop them consistently until researching the best solution possible. We also carry out activities to spread the power electronics technology to many people.

A Day in the Lab

At the Haga laboratory, there is no fixed work hours, students are free to decide their own research schedule. Although it opened just four years ago, the students in this laboratory are full of motivation. With students developing their research freely, while reporting their progress and doubts to the professor every week, it is truly the best environment for growing as electronics students. Because of professor haga's karate background, he treasures both the spirit and mind strength. This is why he encourages his students to practice sports such as fitness, muscletraining and any other activities outside of the laboratory.
