| Outline of Final Research Achievements |
The active gate control is employed for the parallel-connected power semiconductor devices and current unbalancing is minimized using active gate control methodology. This 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. Further the research analysis is performed on the gate signal characteristic study corresponding to the active gate control. The correlation between the device current unbalancing and Miller plateau is realized. A parallel hybrid switch is developed with specific gate driver and inbuilt delay for the appropriate hybrid switching.
