    Abstract: A feedback control system for use with ultrasonic welding. A weld energy set point and/or a reference power curve are used by a controller to provide a power supply voltage set point and a power supply frequency set point for the power that is to be drawn by an ultrasonic weld generator. Information regarding the actual voltage and/or frequency of the drawn electrical power, and/or the frequency and magnitude of an ultrasonic wave transmitted from the generator to an applicator tool used to weld an object can be utilized by an estimator to estimate the weld energy dissipated at the weld site and/or generate a power curve for the welding operation. Using information from the estimator, the controller can determine adjustments for variables for the current and/or future welding operations. Further, welding may not commence until a clamping force exerted on the object satisfies a clamping force set point.

    Abstract: A method for predicting power converter health is provided. The method comprises receiving a plurality of parameter measurements associated with a power converter system comprising a power converter. The plurality of parameter measurements comprises a first set of system measurements and a second set of failure precursor measurements. The method further comprises inputting the first set of system measurements into a first machine learning algorithm to generate expected failure precursor measurement information and inputting the expected failure precursor measurement information and the second set of failure precursor measurements into a second machine learning algorithm to generate component failure prediction information. The method also comprises performing one or more actions based on the generated component failure prediction information.

    Abstract: A method for an auxiliary device of an auxiliary resonant commutated pole inverter (ARCPI) to determine a boosting time of the ARCPI is provided. The auxiliary device includes an auxiliary switch path that uses a resonant inductor with at least one saturable inductor. The method includes: calculating, by a processor of the auxiliary device, a first boosting time in the auxiliary switch path based on a theoretical resonance inductance and a voltage that are applied to the resonant inductor; determining, by the processor, a second boosting time in the auxiliary switch path based on a look-up table; and determining, by the processor, the boosting time in the auxiliary switch path based on the first boosting time and the second boosting time. The method further includes controlling, by the processor, boosting current of the ARCPI based on the boosting time in the auxiliary switch path.

    Abstract: A zero voltage detection device may include a voltage divider that scales down a first voltage to a second voltage, a comparator that compare the second voltage to one or more voltage thresholds and outputs a first set of signals indicative of an estimation of the first voltage approaching a zero-voltage instant, the one or more voltage thresholds configured to compensate for a time delay from the voltage divider, a flip flop that obtains the first set of signals and outputs a second set of signals to control a switching operation of a switching device, and a control system that obtains the second set of signals during a defined time window and that forces the switching device to turn on at an end of the defined time window if the second set of signals is not detected to limit turn-on losses.
