In this paper, a new voltage-boosting converter, combining the charge pump and the coupling inductor, is presented, together with a passive voltage-clamping circuit which pumps some portion of the snubber energy to the output so as to increase the efficiency at light load. Finally, some derivations, and simulated and experimental results are provided to demonstrate the effectiveness of the proposed...
Integrating various interface converters of small-rated distributed generators into the power system has become a promising solution to rapidly increasing demand of premium electric power. The output voltage of distributed generators, such as PVs, is usually so low that a low-frequency coupling transformer is required to place between the interface inverter and the grid for proper power delivery....
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
