Energy supply module as a two-port network, use of a separating device in such an energy supply module, and method for operating such an energy supply module

An energy supply module comprising:

• an input gate for connection to a power source and an output gate configured as an interruption-free power supply, wherein the input gate and the output gate are through-connected separably via an electrical separating device, and
• an auxiliary energy source connected or configured for connection in parallel with the input gate and the output gate, wherein the separating device is positioned between the auxiliary energy source and the input gate,
• wherein the auxiliary energy source comprises a rechargeable energy store,
• wherein the energy supply module is configured to charge the energy store via the input gate,
• wherein the energy supply module has a charging unit, which is arranged parallel to the switching device, and
• wherein the separating device comprises a circuit arrangement having two transistors and two diodes, wherein the transistors are connected reversely in series, and a diode is connected to each transistor, inversely to the current direction of said diode.
