- the diode is a semiconductor diode with pn junction or a Schottky diode. This technical advantage is achieved, for example, that overvoltage in the ⁇ circular efficiently can be dissipated.
- the memory system comprises a resistor which is connected in series with the diode.
- the resistor has a size of 0.1 ⁇ to 100 ⁇ , preferably 1 ⁇ to 10 ⁇ . This is for example the technical advantage is achieved that damage to the diode is prevented due to high performance.
- the diode is a high-current diode with a permissible breakdown current of greater than 60 A.
- the technical advantage is achieved that overvoltages can be short-circuited with high currents without the diode is damaged.
- the diode is a Zener diode, an avalanche diode or a suppressor diode. This example just ⁇ if the technical advantage achieved by the efficient voltage stabilization is achieved.
- the memory system comprises further zener diodes, which are connected in series with the zener diode.
- the memory system comprises a DC voltage converter for increasing the DC voltage of the energy store.

- the diode comprises a cooling. This game, be achieved at the technical advantage ⁇ that Be ⁇ damage the diode can be prevented by heat.
- the cooling is realized by a contact of the diode with a heat sink. As a result, for example, the technical advantage achieved that the cooling can be realized with a ge ⁇ wrestling effort.
- Fig. 1 is a view of a memory system
- Fig. 2 is a characteristic of a diode.
- Fig. 1 shows a view of a memory system 100 for SpeI ⁇ Chern electrical energy.
- the memory system 100 comprises an energy store 101 for generating a DC voltage, a converter 103 for converting the DC voltage into an AC voltage, which is connected via an intermediate circuit 105 to the energy storage 101; and a diode 107 reverse-connected in the DC link 105 in parallel with the power storage 101 and the inverter 103 to limit a voltage in the DC link 105.
- the inverter is an inverter for converting the DC voltage to an AC voltage. This produces a parallel connection of the diode 107 in the reverse direction in the intermediate circuit 105 of the energy store 101 and of the converter 107.
- the energy storage 101 may be a mechanical, an electrical, electrochemical, a chemical energy storage or a heat storage.
- a mechanical energy storage is for example a flywheel (flywheel), a pumped storage power plant ⁇ or a pressure accumulator.
- An electrical or electrochemical energy store 101 is, for example, a super-capacitor or a battery.
- a chemical energy storage 101 uses, for example, hydrogen, methane or methanol. In contrast, uses a heat storage
- the diode 107 in the intermediate circuit 105 can be embodied as a p-n-doped semiconductor crystal transition or as a metal-semiconductor junction (Schottky diode).
- the diode 107 may also be designed as a Zener diode. In this case, a series connection of Zener diodes is advantageous in order to achieve the required breakdown voltage.
- the inverter 103 is, for example, an inverter or inverter for converting the direct current into an alternating current having a predetermined frequency.
- the memory system 100 comprises a combination of diode 107 and resistor 109, so that not the complete power is applied to the diode 107.
- the resistor 109 used is typi cally dimensioned ⁇ between 1 ⁇ and 10 ⁇ .
- the area may to 0.1 ⁇ to 1 ⁇ , and between 10 ⁇ and 100 ⁇ he ⁇ be got. Also possible are resistors smaller than 0.1 ⁇ and larger than 100 ⁇ .
- the diode 107 serves as passive overvoltage protection to limit the voltage in the DC link.
- the intermediate circuit 105 can be protected passively. This represents an overvoltage protection, which is guaranteed until the breakdown voltage of the diode 107 is exceeded.
- the diode 107 becomes conductive and then acts as a bypass. The voltage in the intermediate circuit Zvi ⁇ 105 or energy storage 101 to rise no further, and the excessive current flows through the diode 107th
- both the maximum voltage of the memory system 100 is limited and allows a bypass current through the diode 107 during operation.
- an over- Monitoring the voltage by means of a voltage measurement, controllable contactors and a controller with software accounts. Therefore, a passive surge protection of the overall system is ensured by means of simple components, which must not be monitored by means of software or mechanical compo nents ⁇ includes.
- FIG. 2 shows a characteristic of the diode 107, which allows a voltage breakdown as of a negative voltage. Up to this point, the diode 107 is almost without current flow.
- the characteristic curve of the diode 107 comprises a breakdown region 205, a stopband 203 and a passband 201. In the stopband 203, the current rises up to the first stop
- the memory system 100 includes incorporating one or more reverse biased diodes 107 into the intermediate circuit 105 of an energy storage 101 connected to an inverter 103, such as an inverter or AC / DC converter.
- a Hochstrom e execution of the diode 107 with a zu ⁇ permissible current greater than 60 A is also possible, so that the resistor 109 can be replaced. Due to the transient behavior of the converter 103 and the diode 107, current only briefly reaches when the diode breakdown voltage is reached, for example, shorter than ls. In this case, only short-term performance occurs at the diode 107. In Lan ⁇ Ger power, cooling of the diode may be seen ⁇ 107 before, for example via a befes- saturated at the diode heat sink. In general, it is possible to use a plurality of diodes 107 in series in order to reduce the resulting power per diode 107. A parallel connection a plurality of diodes 107 is another way to reduce the on ⁇ falling power per diode 107.
- the voltage in the intermediate circuit 105 is typically between 500 V and 800 V. This voltage range can, however, be extended as desired.
- a DC-DC converter i. a DC / DC controller, are used to realize a first voltage increase of the energy storage device 101.
