摘要： A method for operating an inverter with reactive power capability that includes a voltage link circuit and an unfolding bridge, wherein poles of the voltage link circuit are configured to be selectively connected to terminals of an AC output in different configurations by means of the unfolding bridge, in order to change a polarity of the AC output relative to the voltage link circuit. The method includes in the case of a phase shift between an AC current (I) and an AC voltage (U) at the AC output reversing the direction of a current flowing via the voltage link circuit. Reversing the direction of the current flowing via the voltage link circuit includes disconnecting the AC output from the voltage link circuit, providing a freewheeling path between the terminals of the AC output, while the AC output is disconnected from the voltage link circuit, and reconnecting the AC output to the voltage link circuit with the polarity of the AC output relative to the voltage link circuit being changed by the unfolding bridge.

摘要： A half-bridge of a bidirectional converter is divided into a first and a second conduction path connected in parallel. In each of the conduction paths a switching element and a freewheeling diode are connected in series, and the center points of the conduction paths are connected via a second inductor. The second inductor is connected in series with a first inductor which is connected to the center point of the second conduction path. The half-bridge has two operating modes. In each of the two operating modes the switching element in one of the two conduction paths is clocked at a high frequency to cause a flow of energy in one of two directions between a pair of high voltage-side connections and a pair of low voltage-side connections to the half-bridge. The two switching elements are of different types, the switching element in the first conduction path causing higher switching losses.

摘要： An inverter for a photovoltaic system includes a substantially planar baseplate having a front and a rear, wherein the rear forms an outer rear wall of the inverter, and having at least one platform-like elevation that rises in the direction of the front of the baseplate. The inverter also includes a printed circuit board having one or more heat-generating components mounted thereon, wherein the printed circuit board is installed on the baseplate such that the one or more heat-generating components are arranged on the printed circuit board in the region of the platform-like elevation and are in thermal contact with the platform-like elevation. The inverter further includes a potting compound that fills a space on the front of the baseplate and surrounds at least partially the printed circuit board, and a cover arranged on or in the potting compound that adjoins the baseplate, so that the baseplate and the cover surrounding at least part of the potting compound form a housing. The inverter also includes at least four DC connectors that are arranged in pairs on at least one of the lateral end faces of the housing and at least part of which is cast in the potting compound, and an AC connector that is arranged on one of the lateral end faces of the housing, wherein electrical contacts of the AC connector are connected to the printed circuit board.
