<p>The device has switching circuits (20, 22) connected with respective lithium-ion-cells (10, 11) and comprising respective switching elements (26, 34) i.e. transistors, and coils (32). A repeater (30) i.e. iron core, is inductively coupled with the coils, where current flows through the coils. The switching circuits are synchronously switched such that electrical energy is transferred from one of the switching circuits to another switching circuit over the coils and the repeater. The repeater is designed as a common coil core, and a demagnetization unit (36) is coupled to the repeater.</p> |
