Abstract: 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.

Abstract: A circuitry arrangement for a solar power plant includes a transformerless inverter for feeding electric power from at least one photovoltaic generator into an alternating power grid, a galvanic separation of all lines carrying current between the inverter and the power grid, and a DC voltage source in an offset path between one electric line at the input side of the galvanic separation and a reference potential. The DC voltage source provides an offset voltage. The offset path includes a DC branch and an AC branch connected in parallel. The direct voltage source is connected in series with a current sensor in the DC branch, and at least one capacitor is arranged in the AC branch. Further, a DC contactor triggered by the current sensor is arranged in the offset path.
