Improved understanding of the design and operation of these devices has led to the successful development of a new generation of high power gate controlled switches. The devices reported here have an 800 volt forward blocking capability. The forward drop is less than 1.7 volts at 100 amperes and the devices turn-off 100 amperes in about 1 microsecond. Testing techniques and procedures have been developed...
An SCR structure is provided with an anodegate which is used to speed up the device recovery and reduce it s turn-off time. The turn-off process of the "Anode-Gate SCR" is analyzed using the charge control approach. Experimental devices are described and the results of measurements are reported.
