Research Topics of
Kawamura Laboratory

Up: Home


In general this laboratory aims for the fusion of the electrical energy and mechanical motion by electronic tools. They may call it "Mechatronics", but we wish to propose somewhat different concept, Motionelectronics - through our research activities.

The fundamentals are power electronics, actuator, and digital control. The tentative future targets are a new electric vehicle and a new biped walking robot.

Current Research Topics

1. new power converter for FCEV (Fuel-Cell EV) using SiC devices

2. Wireless Inverter

3. Soft Switching Inverter

4. new motor (super motor) drive for HEV (Hybrid Electrical Vehicle)

5. autonomous biped walking robot ( MARI-2 )

6. fast walking and running biped robot by ROCOS (robot control simulator )

7. one leg jumping robot (KEN-2)

8. two leg running robot (MARI-3)

9. contactless power supply for Shinkansen

10. independent control for parallelism of UPS's

11. sensorless control of HB type stepping motor

12. Matching filter

14. other projects

Grants and Contracts

The laboratory has been receiving continuous support from Government, industries and University. The average research fund was/is $200,000 (1993-1998), $400,000 (1999-2001), $200,000(2002-3),$300,000 (2004) and $200,000(2005-8).


You can receive the MSEE and PhD degrees from YNU, if you first pass the entrance examinations, and second earn the required credits and finally finish the required thesis. This laboratory can provide an opportunity for a very few foreign students to have a scholarship of Japanese Government. Presently we have two doctoral students from Turkey and China (as of 2008/10). Six students from Tunisia, France, Korea, Brazil(2) and China already finished their degrees. They received the Mombukagakusho scholarship.
