Various embodiments of the present disclosure provide a power device including at least one first conductive element adapted to generate a magnetic field when traversed by a current, and characterised in that it further comprises a Hall sensor electrically insulated from the first conductive element. The sensor and the first conductive element are mutually arranged so as to detect said magnetic field indicative of the current that traverses the first conductive element.

This disclosure describes circuits and techniques for identifying potential problems with control signals for power switches. More specifically, this disclosure describes the use of registers, e.g., volatile or non-volatile storage elements, configured to count the rising and/or falling edges of pulse modulation (PM) signals within driver circuits or other control circuits. By counting the edges of PM signals within driver circuits, signaling problems can be identified based on mismatch between different counters. The techniques may be used by a driver circuit to detect circuit problems, or readout of the registers can be done after device failure, in order to help identify whether signaling problems may have caused the device failure.

A switching regulator is disclosed comprising a high-voltage port, a low-voltage port, n number of switching poles, a magnetic element, and a controller. In turn, each switching pole connects across the high-voltage port and may consist of either one switch and one diode or two switches and two diodes. In turn, the magnetic element comprises a ferro-core having n number of magnetic branches, each of which includes a winding. Each winding start connects to the phase node of a respective switching pole, while each winding finish connects, in common, to one side of the low-voltage port. An n+1.sup.th magnetic branch establishes a defined common-mode inductance which, in combination with transformer action, limits current ripple. The transformer action serves to exchange ripple power between phases such that the need for inductance is greatly reduced.

An arc extinguishing power device driving apparatus and an arc extinguishing apparatus of the present disclosure belong to the electrical field, and are particularly an arc extinguishing power device driving apparatus applicable to an electronic arc extinguishing apparatus for driving a power device. The power device that needs to be driven is connected in parallel to a mechanical switch that requires arc extinguishing, and includes a first voltage detection switch. An input end of the first voltage detection switch is connected to two ends of the power device. The first voltage detection switch is connected in series in a driving loop of the power device. The first voltage detection switch is turned on when detecting that there is a potential difference between the two ends of the power device. A driving signal is transferred to the power device by using the first voltage detection switch, to drive the power device to be turned on. The first voltage detection switch is a semi-controllable switch, or a fully-controllable switch whose threshold is less than an on-state voltage of the power device. The present disclosure has advantages of no need of a semiconductor device with a high withstand voltage, real-time detection on disconnection of a mechanical switch, and low driving energy consumption.
