This article presents the development and experimental performance of a 10-W, all-silicon carbide (SiC), 250 °C junction temperature, high-powerdensity, three-phase ac-dc-ac converter. The electromagnetic interference filter, thermal system, high-temperature package, and gate drive design are discussed in detail. Tests confirming the feasibility and validating the theoretical basis of the prototyp... View full abstract»

In many distributed systems that involve interactions between physical objects, human beings and environment, the precise time of an event is very important. This is particularly true for automated control applications, wherein the knowledge of the exact time of occurrence of a certain event, or the ability to enforce a given action at a precise instant, is crucial for the correct operation of the...

A comprehensive hydrogen (H2) cooling system (HCS) is presented for the cooling of n # 250-MW generators of fossil-fuel power plants. A novel six stage hot redundant structure (S2HRS)-based HCS clubbed with highly reliable and efficient process control and instrumentation system is proposed for the cooling of large generators in integrated gasification combined cycle power plants (CCPPs). This art... View full abstract»

It is apparent that implementation of practical sessions in engineering education paves the way for students to be familiar with instruments and, thus, with the industrial real world. In recent decades, the high cost and administration burdens of physical equipment have caused a significant decline in experimentation within engineering education. This situation has fostered the development and ado... View full abstract»

Today, the architecture of electrical networks is evolving. Distributed dc generation from photovoltaic systems and small wind turbines, the possibilities offered by dc energy storage, the spread of smart grids, and the potential of high- and middle-voltage dc ensured by high-voltage power electronics, enable us to conceive new scenarios with respect to the presently dominating ac high-voltage ene...
