Abstract: A multi-phase multi-stage power converter includes a phase module having a power converter module formed of two-pole submodules connected in series and having a plurality of semiconductor switches connected in series, an energy store charged and discharged by the semiconductor switches, a bypass switch short-circuiting the energy store upon exceeding a first limit voltage, and a signal input for a blocking signal opening all semiconductor switches. The submodules are protected from overloading in a simpler manner by connecting a module arrester in parallel with the power converter module. The module arrester limits the power converter voltage like a valve upon exceeding a second limit voltage. The module arrester operates in blocking mode below the second limit voltage and in conducting mode above the second limit voltage. A current limiting the power converter voltage flows through the module arrester in conducting mode.

Abstract: The invention relates to a dosage form that is suitable for releasing an active ingredient over a long period of time. For this purpose, the active ingredient is released in two-stages in order to do away with an excessively frequent ingestion of the dosage form. The dosage forms according to the invention are for treating dizziness in humans. They are administered with or after a meal. The concept according to the invention provides that the pharmaceutical form has a dimensionally stable portion which, after ingestion of the dosage form by the patients, does not dissolve in the chyme-filled stomach for a number of hours. In this way, this dimensionally stable portion remains in the stomach until same is evacuated by the so-called “housekeeper waves”. Another portion of the dosage form is formed in such a way that it dissolves within a short time of the patients ingesting same. In this way, a quick invasion of the active ingredient with corresponding plasma levels is ensured.

It is proposed that an available cooling power (PV) for cooling the traction battery is determined, wherein as a function of the available cooling power (PV), the magnitude of the mass flow of the refrigerant is regulated in such a way that either no cooling power (Pactual) is delivered to the traction battery, or the delivered cooling power (Pactual) in each case assumes one of multiple cooling power stages (I, II) as a function of the available cooling power (PV).
