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: This invention provides such new and useful methods and systems for accurately comparing treatment efficacy and safety using heterogeneous clinical trials in the absence of a common control group. To accomplish this, the invention leverages both novel regression techniques and novel simulation techniques to normalize heterogeneous clinical trials to a common background, and to analytically isolate the portion of the patient response specifically attributable to a given treatment and not the placebo effect. The sequential regression and simulation techniques of the disclosed methods and systems further allow for the outcomes of subjects of heterogeneous clinical trials to be simulated as a function of treatment and patient-level features, enabling the creation of decision support tools capable of making personalized treatment recommendations.

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.

Abstract: A boost converter has a main energy storage inductor and a main GaN boost switch with a node between them. A pre-charging switch is connected at the output side of the main boost switch and the inductor, between the node and an output capacitor. The pre-charging switch comprises a body diode in the forward direction from the output capacitor to the node. The output capacitor is charged by the pre-charging switch in a pre-charge phase and this provides a soft start-up to avoid large inrush currents. A third switch, which is also a GaN switch, is in series with the pre-charging switch to provide synchronous output rectification. The third switch has a body diode in a forward direction from the node to the output capacitor. In the pre-charge phase, both the boost switch and third switch are turned off whereas in a subsequent boost phase, the pre-charging switch is turned constantly on, and alternately the boost switch and the third switch are turned on and off to implement the boost conversion.
