<p>The bi-directional direct current controller (GS) has switching equipment (S1) and free-wheeling diode (D1), where the switching equipment and the free-wheeling diode are connected in parallel manner. The switching equipment and free-wheeling diode are inserted between a connection (K2) and another connection (K4). An independent claim is also included for a system with energy density.</p> |
