Techniques for implementing an adaptive DC link voltage regulation scheme are described. By adopting an adaptive approach to DC link voltage regulation, such as where the DC link voltage is set as a scaling factor multiplied by the battery voltage, the techniques significantly reduce the switching losses and heat present in conventional two-stage power converters. The techniques use a control system that dynamically adjusts the DC link voltage in real-time, in response to variations in the battery's voltage during the charging cycle. This adaptive regulation of the DC link voltage not only minimizes the heat generated due to switching losses but also optimizes the charging process to suit the requirements of the battery.

To calibrate actuation of the clutches, the traction motor is run at a reduced speed range under calibration conditions while the hydraulic system is operated at a operational speed range. Further, a torque/current limit is applied to the traction motor to limit torque applied to the transmission during calibration.

EQUIPMENT FAILURE IDENTIFICATION AND PREDICTION OF REMAINING USEFUL LIFE USING MACHINE LEARNING
Techniques are disclosed herein for machine-learning (ML)-assisted event prediction for industrial machines. Sensor data for an industrial machine can be modified by generating imputed values. A trained neural network can be executed on the modified sensor data to generate classifier tags for the modified sensor data. The system can generate a binding between the sensor data and the classifier, and generate a notification based on the classifier. The notification can relate to or include a predicted failure, anomaly, usage profile, or remaining useful life estimate for the industrial machine. The system can also generate additional training data to improve predictive capacity of the trained neural network. The additional training data can include additional classifiers determined using sensor signaling channel information or sensor data (e.g., using payload values from sensor signals, metadata values from sensor signals, or metadata associated with a particular sensor signaling channel).

PREDICTION OF EQUIPMENT-RELATED EVENTS USING MACHINE LEARNING
Techniques are disclosed herein for machine-learning (ML)-assisted event prediction for industrial machines. A first set of embeddings can be generated based on labeled first event data, which can be labeled with classifiers determined based on signaling channel information for the first event data. A neural network can be trained, using the classifiers, to generate (i) a similarity score for the first set of embeddings and the second set of embeddings and (ii) a classifier recommendation for the second set of embeddings. The second set of embeddings can be generated based on data collected using condition monitoring sensors for a particular industrial machine. Accordingly, the system can generate alerts, recommendations, and/or notifications based on the automatically classified data encoded in the second set of embeddings. Incremental training techniques are disclosed for further training the neural network to minimize false positives and/or false negatives.
Techniques are described for detecting and isolating ground faults within power converter systems, particularly in high-voltage and high-power applications such as mobile machines. The disclosed techniques monitor an electrical parameter of the system to enable the rapid identification and precise localization of ground faults.

In some implementations, a supervisory electronic control unit (ECU) may output, to a first controller, a first control signal commanding the first controller to provide a first voltage to a first bus during a bleed-down operation. The supervisory ECU may output, to a second controller, a second control signal commanding the second controller to provide a second voltage to a second bus during the bleed-down operation. The supervisory ECU may activate, during the bleed-down operation, a sinking device electrically connected to the first bus and the second bus.

FUEL INJECTOR AND NOZZLE ASSEMBLY CONFIGURED FOR LIMITING CAVITATION DAMAGE
A fuel injector in an engine system includes a nozzle having a plurality of spray orifices, and forming a check seat and a sac. A nozzle check is movable in the nozzle between a closed position in contact with the check seat, and an open position. The nozzle check includes a tip having a flat nib and an outer tip surface profiled to define a seating line for sealing with the check seat. The arrangement is associated with fuel flow patterns having reduced risk of cavitation damage via biasing high-velocity flows of fuel away from an outer sac wall. Related apparatus and methodology is also disclosed.
Systems and methods are disclosed herein for identifying and predicting maintenance events with respect to assets, such as mobile machinery. A computing platform can include control circuit(s) (on-board and/or remote) configured to acquire machine fault data and machine utilization data. A feature set can be generated by transforming the machine fault data (e.g., by fusing the machine fault data with machine utilization data), normalizing the data, generating embeddings, and/or executing imputation algorithms to fill in missing values. A classifier model can be trained using the transformed machine fault data in conjunction with labeled maintenance event data to enable the trained classifier model to learn to recognize utilization-specific fault code patterns. The trained classifier model can generate inferences and predictions regarding machinery maintenance events without the use of maintenance data.
