摘要： The disclosure relates to an inverter for supplying a power provided as a DC voltage at a DC input to an AC mains connectable to an AC output. In this case, the inverter includes a switching network with a plurality of semiconductor switches and a digital control unit for producing a digital switching pattern for digitally operated semiconductor switches of the switching network that are able to be used to produce a first output voltage (Uout,dig). The inverter additionally includes a linear control unit for producing signals for actuating at least one semiconductor switch of the switching network in a linear mode, wherein the linear control unit is set up to produce a voltage drop (Uout,lin) across and/or a current (Iout,lin) through the at least one linearly operated semiconductor switch to a target value that is dependent on an instantaneous difference between the first output voltage (Uout,dig) and a voltage (UAC) of the AC mains. The disclosure additionally relates to a control method for such an inverter and a photovoltaic (PV) installation having such an inverter.

摘要： An inductor apparatus includes an inductor winding, a core defining a magnetic circuit for a magnetic flux generated by a current flowing through the inductor winding, at least one permanent magnet magnetically biasing the core by its permanent magnetization, and a magnetization device operable for adjusting a desired magnetization of the permanent magnet. The at least one permanent magnet is arranged within the magnetic circuit of the magnetic flux generated by the current flowing through the inductor winding. The magnetization device includes a magnetization winding and a circuitry configured to subject the magnetization winding to magnetization current pulses, thereby generating at a location of the permanent magnet a magnetic field which is able to change the permanent magnetization of the permanent magnet.

摘要： The disclosure relates to a DC/DC converter including at least one clocked switching member and at least one inductor which is arranged between an input connection and an output connection of the DC/DC converter and is for intermediate storage of energy transferred by the DC/DC converter, wherein the inductor has a core with permanent magnetization. The DC/DC converter is configured for bidirectional operation, wherein, in a first energy transfer direction, the at least one switching member is switched in a first operating mode and, in a second energy transfer direction which is opposite to the first, the at least one switching member is switched in a second operating mode which deviates from the first. The disclosure also relates to an operating method for a DC/DC converter.
