초록

A concern about micro grid connection system is elevated. The reason is that carbon dioxide emission is regionally restricted to prevent the drain of fossil fuel, high oil prices and global warming. The existing photovoltaic DC-DC converter is operated by the full-bridge method. However, the configuration is complicated because a phase shift method is required to raise an efficiency. A photovoltaic DC-DC converter connected with second layered half-bridge converter and boost converter is proposed in this paper. This proposed DC-DC converter is easy to control and has an advantage of reducing the size. Finally, the validity of the proposed converter is verified by the experimentation.
