<p>A device (3) and method for balancing voltages of energy storage elements (4). The device (3) includes at least one transformer (36) and at least one bi-directional DC/AC conversion circuit (35). Each transformer (36) includes at least one transforming winding (26, 27) and at least one equalizing winding (30). The DC terminals of each bi-directional DC/AC conversion circuit (35) are connected with the positive terminal (41) and the negative terminal (42) of each energy storage element (4), and the AC terminals are connected with the transforming windings (26, 27) of the transformers (36).</p> |
