Abstract:
1. A system that balances voltages between battery banks, comprising: a plurality of battery banks, including a first bank and a second bank; a first capacitor with a first terminal and a second terminal; a second capacitor with a first terminal and a second terminal; a first set of switching devices which selectively couple the first and second terminals of the first capacitor to first and second terminals of the first bank, and first and second terminals of the second bank; a second set of switching devices which selectively couple the first and second terminals of the second capacitor to the first and second terminals of the first bank, and the first and second terminals of the second bank; and a clocking circuit which generates clock signals with substantially non-overlapping clock phases, including a first phase and a second phase; wherein the clocking circuit is configured to:
