| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, with the depletion of fossil reserves and the increase in pollution, to achieve a high power density and efficiency in electronic devices becomes a key point. In addition, since the smaller TEC values of OA equipment are requested, it is necessary to realize a high efficiency in a wide operating range from the energy-saving mode to the rated mode. Furthermore, the coexistence of energy saving and low cost is hard to be achieved in conventional power supply. In this paper, a new DC-DC converter with a serge energy regeneration circuit topology is studied. A small inductor is positively attached to the power transformer to realize a high efficiency and a low noise performance. The circuit operation analysis and the results of both simulations and experiments are shown. Finally, various circuit topologies are built to carry out the efficiency comparison and loss analysis to clarify the features of each other. |
