Abstract: The subject matter disclosed herein relates to semiconductor power devices, such as silicon carbide (SiC) power devices. In particular, the subject matter disclosed herein relates to shielding regions in the form of body region extensions for that reduce the electric field present between the well regions of neighboring device cells of a semiconductor device under reverse bias. The disclosed body region extensions have the same conductivity-type as the body region and extend outwardly from the body region and into the JFET region of a first device cell such that a distance between the body region extension and a region of a neighboring device cell having the same conductivity type is less than or equal to the parallel JFET width. The disclosed shielding regions enable superior performance relative to a conventional stripe device of comparable dimensions, while still providing similar reliability (e.g., long-term, high- temperature stability at reverse bias).

Abstract: A switching system includes a control circuit that receives On-Off signals indicative of a desired operating state of a switch. The control circuit includes an oscillator that generates a first electrical pulse responsive having a first signal characteristic or a second signal characteristic that is determined by the received On-Off signal, which may be related to a frequency or duty cycle of the pulse. A pulse transformer connected to the oscillator receives the first electrical pulse and outputs a second electrical pulse having the same one of the first signal characteristic and the second signal characteristic as the first electrical pulse. A pulse detection circuit in the control circuit receives the second electrical pulse, determines whether the second electrical pulse has the first signal characteristic or the second signal characteristic, and controls transmission of power and control signals to the switch based on this determination.
