专利汇可以提供GRID FEED APPARATUS, ENERGY FEED SYSTEM AND METHOD FOR OPERATING A GRID FEED APPARATUS专利检索,专利查询,专利分析的服务。并且The invention relates to a grid feed apparatus (10) for feeding electrical energy from a DC energy source (12) into a three-phase AC supply grid (32), wherein the DC voltage of a DC intermediate circuit (24) is converted into a three-phase voltage by means of at least one inverter device (14) and is fed into the AC supply grid (24) by means of a transformer device (16) comprising three grid transformer windings (38). The invention is characterized in that a first winding connection of the grid transformer windings (38) is connected to a half-bridge (30) of a first inverter device (14a), and a second winding connection of the grid transformer windings (38) of the transformer device (16) is connected to a half-bridge of a second inverter device (14b). In other aspects, the invention relates to an energy feed system for connecting a photovoltaic source, a fuel cell source, a rechargeable battery source or a mechanically driven DC generator to an AC supply grid or to an AC load, in particular three-phase motor, or to an operating method for energy-efficient voltage feed.,下面是GRID FEED APPARATUS, ENERGY FEED SYSTEM AND METHOD FOR OPERATING A GRID FEED APPARATUS专利的具体信息内容。
