| Outline of Annual Research Achievements |
The device characteristics has been studied considering the paralleling of the devices and understands the problems that is associated with paralleling.
The experimental system for this study is under development to perform the real-time operation of parallel-connected devices and observe the unbalancing phenomenon during parallel operation. The active driving methodology is under development to test it with real-time operation and obtain the improved the paralleling of the power devices.
To test the device operation under parallel operation at high voltage is also vital considering the application in high power system. The safety box for high voltage experiment is also under development with interlocking and high voltage discharge functionality for risk free experimental environment.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Last year April, received the research grant for the three years. At that time, I was working as a post-doctoral researcher. Meanwhile there was corona virus emergency. In the October last year, moved to the another university as an assistant professor. In previous university, already had the basic infrastructure and experimental system to start with the research work.
The entire system and infrastructure required to be build from the scratch in the new university as well as the laboratory is very new so even did not have the basic components, items and software licenses. Everything is started from the zero and it has taken time to restart with the research work.

| Strategy for Future Research Activity |
1) The completion of the basic experimental study of parallel device system.
2) Development of high-voltage experimental set-up.
3) The experimental study of parallel-device for high voltage operation and measurement circuitry.
4) The implementation of gate control for active balancing of parallel operation.
