In this paper, by change of integration path in complex spectrum domain and by defining input admittance as the ratio of complex radiated power to amplitude of square of voltage across the gap, new expressions of admittance (valid for all frequencies) of infinitely long cylindrical antenna with and ...

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...

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...

Rapidly decreasing prices for renewable energy, increasing industrialization and electrification of the global economy, and a world-wide focus on reducing carbon emissions, is causing a reexamination of the power system of the future. A reliance on centralized planning and control, scheduled and dis...
