Abstract :
In recent years, environmental problems and consumer requirements encourage more and more high efficiency and miniaturized electronic devices. In addition to that, since smaller Typical Electricity Consumption (TEC) values of office automation equipment are requested, it is necessary to realize high efficiency in a wide operating range from the energy saving mode (about 0.5W) to the rating mode (about several hundreds of watts). 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 surge 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 addressed. In this paper, various circuit topologies are built to carry out the efficiency comparison and performance evaluation with TEC values.
