  • Input voltage dependent control for active clamp flyback
    Patent number: 11336190
    Abstract: A method for controlling a power converter includes turning on a power switch to maintain a desired output voltage, wherein the power switch is coupled to a primary winding to control a primary current flow and the output voltage is provided by a secondary winding. The method also includes adding a capacitance in parallel to the power switch at a time determined by a magnitude of an input voltage to the power converter. Here, the timing of adding the capacitance depends on the operation mode of the power controller. In a low input voltage mode, the capacitance is added in a demagnetization-time during which the secondary winding discharges. In a high input voltage mode, the capacitance is added in a discontinuous time.

  • Micro assembler with fine angle control
    Patent number: 11302554
    Abstract: An assembly surface has an array of electrodes arranged such that each of a plurality of chiplets can be positioned to cover at least one of the electrodes. A field generator applies a rotation field that is orthogonal to the clamping force field applied by the electrodes. A processor is operable to determine a desired orientation angle of a first subset of the chiplets and activate one or more of the electrodes so that a second subset of the chiplets different than the first subset is kept from rotating by a clamping force field applied by the one or more of the electrodes. While the clamping force field is being applied, the processor applies the rotation field at the selected angle to cause the first subset of the chiplets to be oriented at the desired orientation angle.
