  • Patent number: 12273096
    Abstract: A driver circuit is for driving a GaN power commutation switch of a switch mode power converter. A sensing component is connected to the GaN switch for sensing a parameter such as a peak current of the power commutation. An energy storage component provides a certain turn on voltage between the gate and source of the GaN switch. The charging and discharging of the energy storage component is regulated, and the sensing is disabled with timing which is synchronized with the charging and discharging function of the energy storage component. It is prevented that a voltage across the sensing component reduces the generated gate-source drive voltage of the GaN switch.

    Abstract: A driving circuit and arrangement for driving a load between two output terminals. The driving circuit comprises an input and output terminals connected to the input. A fault detection inductor is connected in series with the output terminals, and is configured to modify an electrical parameter through a feedback inductor responsive to a change in current between the output terminals. The feedback inductor is galvanically isolated, but magnetically coupled, to the fault detection inductor. The driving circuit further comprises a first current sensing inductor through which a current provided by the converter passes, and the feedback inductor is also galvanically isolated, but magnetically coupled, to first current sensing inductor. Thus the feedback inductor can be induced with signal both from the first current sensing inductor and the fault detection inductor and saves components, space, and cost.
