摘要： The invention relates to a DC/DC converter for use in a decentralized power generation system. If a DC/DC converter is physically separated from a power receiving component and connected to such a power receiving component via a DC bus, a short-circuit on the DC bus may endanger the system and service personnel. In order to minimize such a risk, it is proposed that the DC/DC converter comprises a converting component for DC/DC converting a direct current supplied by a power generating unit and for supplying a resulting converted direct current to a DC bus, and that the DC/DC converter comprises in addition a control component arranged to monitor a voltage at the outputs of the DC/DC converter and to cause the converting component to enter a short-circuit protection mode if the monitored voltage lies below a predetermined voltage threshold. The invention relates equally to a corresponding system and to a corresponding method.

摘要： The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.

摘要翻译： 本发明涉及一种用于根据电气输入提供输出的电气设备。 如果电输入处于第一电输入范围中，则电气设备（1）适于提供恒定输出，如果电输入处于第二电输入范围，则依赖输出，其中相关输出取决于 电输入。 因此，即使优选为直流电网电压的电输入在第一电输入范围内波动，输出也可保持恒定。 此外，在第二电输入范围中，可以通过仅仅控制诸如直流电网电压的电输入来控制输出，而不一定需要电气设备的附加控制结构。 因此，可以以相对简单的方式实现电输入的波动阻力和输出的可控制性。
