This paper presents some practical issues and experience acquired in the design and experimental verification of a small-sized solar concentrator producing both electrical and thermal power. The device is a low-concentration photovoltaic/thermal solar system with a 20 suns ($20\times $ ) concentrator factor and is suitable for integration on building roofs. It consists of four small-sized ($1930 \times 250 \times 166$ ...
This paper presents the analysis and design of an inductively-coupled wireless power transfer system implemented using a three-coil arrangement and the Class E2 resonant DC-DC converter. The three-coil structure is modeled using FastHenry simulation software. The theory of reflected impedance is used to determine the optimum operating conditions. A practical application having an output voltage of...
This paper introduces the integration of Class DE inverter with loosely coupled inductors for near-field wireless power transfer (WPT) applications. The benefits of using Class DE inverter in the inverter stage of the WPT system are the low transistor voltage stress and zero-voltage switching (ZVS) of the transistors. The step-by-step integration of circuits using Class DE inverter, tuned loosely...
