The rapid pace of change in the wide band gap (WBG) power semiconductor area has led to an explosion in potential uses for WBG devices in a huge variety of applications. The applications include automotive, aerospace and traction applications, as well as grid related or charging systems, with the po...

Power converters are the typical switched systems which operate based on the alternate switching of the semiconductor switches. The operating mode of power converters consists of several operating stages in one switching period. Each operating stage refers to a sub-circuit or equivalent circuit wher...

A wide speed range permanent magnet synchronous generator (PMSG) system is studied in this paper, including the PMSG design and comparative study on control strategies with a pulse width modulation (PWM) rectifier, the purpose of which is to regulate the DC-link voltage. It is of great importance to...

We report a novel self-powered nanocomposite sensor composed of K_0.5Na_0.5NbO₃ (KNN) nanoparticles (NPs) and multiwalled carbon nanotubes (MW-CNTs). The KNN NPs and MW-CNTs are dispersed in polydimethylsioxane by mechanical agitation to produce a piezoelectric nanocom...

In today's power electronics products, quality and reliability are given. Great emphases are placed on high efficiency, high power density and low cost. With recent advances made in gallium nitride power devices (GaNs), it is expected that GaNs will make significant impacts to all three areas mentio...
