Abstract: A networklized DC power system includes: a micro DC grid, and a plurality of energy routers connected to the micro DC grid. Each of energy routers includes a controlling module for controlling the energy router. A DC receiving port is coupled for receiving DC power from at least one DC power generating system. An AC receiving port is provided for receiving AC power from an AC power supplying system. A battery charging/discharging port is connected to a battery system for charging or discharging the battery system. A DC outputting port is provided for applying DC voltage to a load. A network interface port is coupled to the micro DC grid, and for receiving the power from the micro DC grid or for transferring power to the other energy routers of the micro DC grid.

Abstract: A shared power system includes a power router; a plurality of power input devices respectively connected to the power router; a first diode coupled between the power router and an output; a second diode coupled between a DC grid and the output; wherein the power router can provide power to the output by conducting the first diode when voltage of the power router is higher than the DC grid, and the DC grid can provide power to the output by conducting the second diode when voltage of the DC grid is higher than the power router. The power router can further determine the energy ratio between each power input device to achiever the energy-sharing.
