Advantages and disadvantages of Ultrasonic Machining 2. Ultrasonic Machining • In ultrasonic machining (USM), also called ultrasonic grinding, high- frequency vibrations delivered to a tool tip, eedded in an abrasive slurry, by a booster or sonotrode, create accurate cavities of virtually any shape; that are, “negatives” of the tool.
When comparing silicon carbide MOSFET with silicon superjunction MOSFET, there are two major advantages for silicon carbide MOSFET. Firstly, silicon carbide MOSFET has the lowest specific Rds(on), especially for higher than 650 volt devices, due to its intrinsic and material properties, including high energy bandgap and high critical electric field.
