Abstract: The technology of this application relates to a partial power converter that is configured to be connected to at least one photovoltaic panel as inputs and a direct current output bus, the at least one photovoltaic panel generating a direct current. The partial power converter includes a photovoltaic-side converter comprising at least two switching cells, a bus-side converter comprising at least two switching cells, the bus-side converter being configured to switch a total current of the photovoltaic-side converter, an energy storage element connected between the photovoltaic-side converter and the bus-side converter, and an indirect voltage source configured to regulate the energy storage element. The photovoltaic-side converter, the bus-side converter and the energy storage element are connected in parallel between the first node and the second node of the partial power converter.

Abstract: The present invention provides a mobile terminal and method for display of detailed information regarding digital rights management (DRM) contents in an intuitive and direct manner for the user. The detailed information includes information items that are attributes of the DRM contents (such as types, sizes, and created dates) or usage rights in licenses of the DRM contents (rights to play, display, execute, print, and export the DRM contents). Those information items associated with selected DRM contents are displayed using text or icons.

Abstract: A real-time detail information display method of digital rights management (DRM) contents and a portable terminal for practicing that downloads digital rights management (DRM) content information from a server, in real-time. The portable terminal extracts address information of the DRM contents indicated on the display, accesses the server based on the extracted address information, and receives the DRM content information from the server and displays it on the display.
