Patent ID: 7307859

Claim:
A device for transmitting energy, comprising one return vertex and at least a primary winding set and secondary winding sets, wherein each secondary winding set comprises: at least one winding; at least two diode edge pairs, wherein each pair has a positive diode and a negative diode; at least two pole vertices, each pole vertex positioned between the positive diode and the negative diode of each diode edge pair such that each pole vertex has a voltage that may be substantially determined via the positive diode, the negative diode, or both; at least two throw vertices, each throw vertex activated by the positive diode, the negative diode, or both to substantially determine the voltage transferred to the pole vertices; and at least two capacitors; each connected to one of the throw vertices; wherein there is substantially no AC voltage between secondary winding sets; each secondary winding set shares at least a throw vertex with an adjacent secondary winding set; each secondary winding set closes at least a single closed path which does not include a winding of another secondary winding set, and closes at least a second closed path that includes the at least one return vertex included in the return path of another secondary winding set; throw vertices of each secondary winding set operate at a substantial DC bias relative to the second closed path; and substantially all current related to energy transfer between primary winding sets and secondary passes through a shared portion of the return path.
