摘要

According to Fraunhofer ISE, the Cell-Booster and the power electronics for the project "Netefficient" permit high efficiencies on the one hand, and small construction volumes on the other. The cell booster converts the typical 48 volt output of a low voltage battery with an efficiency of 97% to 700 volts, as required for example by a three-phase battery inverter. According to Stephan Liese, Head of Group Distributed Generation and Storage, the key factor enabling this high efficiency is the high frequency with which the transformer is operated and which is even modulated. According to Liese, efficiency levels of between 90 and 95% are customary in the market for comparable applications. In addition to the increased efficiency, the high frequency also helps to reduce the size of the housing.
