    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： In order to measure a choke current (I) flowing through a choke (1), a flux density (B) of a magnetic field (8) emitted from the choke (1) is measured continuously with a sampling rate at a location which is stationary relative to the choke (1). A magnetic bias of the choke (1) is ascertained from the measured values of the flux density (B) when a known choke current (I) occurs during the ongoing operation of the choke (1). The choke current (I) is known only at time intervals longer than the reciprocal value of the sampling rate when measuring the flux density (B). The current choke current (I) is determined while taking into consideration the magnetic bias ascertained from the current measured values of the flux density (B).

    摘要： A protective device for a photovoltaic system includes at least one input for connection to a photovoltaic generator and at least one output for delivery of an electric power supplied from the photovoltaic generator. The protective device includes a detection device for a signal applied via the at least one output, and is configured to provide a low level-limited voltage at the at least one output if an applied signal does not meet a predetermined criteria, and is further configured to connect the at least one output with low resistance to the at least one input via a switching device if the applied signal meets the predetermined criteria.
