Patent ID: 8779700

Claim:
A system for use with a voltage source and a load and a capacitor, the voltage source defining first and second nodes, the capacitor connected to the second node and thereby defining a third node, the load connected with the first node and the third node, the voltage source comprising a plurality of series-connected energy sources; a module connected with the energy sources of the voltage source, the module connected with the capacitor at the second node and the third node; the module comprising an inductor; the module further comprising a plurality of first bidirectional circuits, each first bidirectional circuit connected with a respective energy source of the voltage source and connected with the inductor; the module further comprising a second bidirectional circuit, the second bidirectional circuit connected with the capacitor and connected with the inductor; the module further comprising a controller connected with the first bidirectional circuits and with the second bidirectional circuit and disposed to control the bidirectional circuits to pass energy therebetween.
