  • Patent number: 4742243
    Abstract: An electric circuit consolidates electric power from a number of power sources, having various voltage levels and connected to form a grid and delivers the power to a common load. This is accomplished by interposing switching elements in the connection or nodes between the terminals of the grid and the busbars that feed the load. These switches operate in a manner such that all the sources contribute to the output power. However, at any given time, only two nodes on the grid are connected to the load. Alternating current is derived from a direct current grid by using sets of switching elements to reverse polarity of the voltage supplied to the load.
