| 研究開始時の研究の概要 |
The scientific and technological evolution of state-of- the-art devices since its inception has made a leap in power rating. This ultimately leads to extend the horizon for operating range of a single device considering blocking voltage and current capability. However, higher current/voltage ratings of power devices are required for high power conversion and control Enhancement and optimization of the performance of power semiconductor devices are of fundamental concern, especially for the system consisting of parallel/series connected devices.

| 研究成果の概要 |
The active gate delay control is implemented for the SiC power devices as well as the IGBT power devices. The active gate control strategy is employed under the dynamic operation of the device that is turn-on and turn-off. A parallel hybrid switch is developed with gate driver and inbuilt delay.

| 研究成果の学術的意義や社会的意義 |
The electrification is necessary to tackle the problem of CO2 emission. The paralleling of the devices are used in high power converters for electrification, the current unbalancing problems addressed in this research will help to create an understanding and possibly provide a solution.
