<p>PCT No. PCT/DE95/00791 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Jun. 13, 1995 PCT Pub. No. WO96/04564 PCT Pub. Date Feb. 15, 1996A method and apparatus for allowing charge exchange among a plurality of energy accumulators of the same type which are interconnected in series. At least one electric accumulator is cyclically and alternatively connected in parallel to the energy accumulators. Each electric accumulator consists of a capacitive element charged by the energy accumulators. The electric accumulators are also each cyclically connected in parallel to one of the energy accumulators, so that during each phase of the cycle al energy accumulators of the same type are individually connected in parallel to an electric accumulator thereby establishing a direct power flow from higher voltage accumulators to lower voltage accumulators. The method and apparatus may be used for equalizing the charge of energy accumulators, and energy converters.</p> |
