Abstract: A wide bandgap semiconductor device with an adjustable voltage level includes a wide bandgap semiconductor power unit and a level adjusting unit. The wide bandgap semiconductor power unit includes a source terminal, to which the level adjusting unit is electrically connected. The level adjusting unit provides a level shift voltage via the source terminal to adjust a driving voltage level of the wide bandgap semiconductor power unit. By adjusting the driving voltage level of the wide bandgap semiconductor power unit using the level adjusting unit, the wide bandgap semiconductor device may serve as a high-voltage enhancement-mode transistor to achieve reduced costs and an increased switching speed.

Abstract: Embedded system with web-based user interface, firmware structure thereof, and method for providing information thereof are provided. The firmware of the embedded system includes an execution part and a presentation part, which are separated, wherein the execution part includes a web service program and a program interface while the presentation part includes a web page which includes a request for dynamic content associated with the program interface so as to obtain corresponding dynamic content. When the system takes the presentation part as the static content of its web-based user interface, the web service program, in response to a static content request, reads the web page from the non-volatile memory and outputs it to a device, and in response to the dynamic content request, invokes the program interface to obtain the corresponding dynamic content and output it to the device.
