    摘要： A power switch assembly comprises a power switch, a driving circuit configured to control the power switch, a protection device having a first current duration and a first current value and arranged between the driving circuit and the power switch, the protection device being configured to decouple the driving circuit from the power switch based on the first current duration and the first current value, and a clamping device having a second current duration and a second current value and arranged between the driving circuit, the protection device and the power switch, the clamping device being configured to couple the power switch to a second assembly load terminal of the power switch assembly based on the second current duration and the second current value. The first current duration is longer than the second current duration. The first current value is lower than the second current value.

    摘要： A primary power supply input is supplied to each of gate driving units 21 to 26 through individual transformers T1 to T6, respectively, from power supply terminals 101 and 102. One end of a primary winding of each of the transformers T1 to T6 is connected to the power supply terminal 101 by power supply lines 31 and 32. In addition, the other end of each of the primary windings is connected to one another by common connection lines 33 and 34 to be further connected to a drain terminal of a MOSFET 27 for controlling a current flowing in each of the primary windings. A gate power supply control circuit 28, to which an output current detected by an auxiliary winding of the transformer T2 is fed back, controls a duty ratio for the on-off control of the MOSFET 27. Thus, a gate driving power supply system is provided in which a transformer is arranged for each of the outputs of individual power supply circuits with their respective control circuits integrated into one to thereby reduce the number of parts.

    摘要： Methods and apparatus for providing power for a gate signal for a semiconductor switching element are described. In some examples, an alternating current is provided on a primary conductor and induces a current in a secondary conductor. Power is derived therefrom to provide a gate signal. A frequency modulation is applied to the alternating current on the primary conductor and detected in the induced current in the secondary conductor. In some examples, the frequency modulation may be indicative of a data signal, for example a gate control signal.
