What changed

The USPTO has granted patent US12583335B2 to Thermo King LLC, covering an inverter apparatus. The patent details a system comprising a controller, an inverter, a load, and a DC link. The controller is designed to detect when an AC electrical component is starting up and, in response, operate the inverter in a protected startup mode. During this mode, the output frequency of the inverter gradually increases to a predefined operating frequency, aiming to protect the component during its startup phase.

This patent grant represents a new intellectual property asset for Thermo King LLC. For compliance officers, this is primarily an informational update regarding a granted patent. There are no immediate compliance obligations or changes to regulatory requirements for other entities. The patent's claims are specific to the technology described and do not impose new rules or standards on the industry.

Abstract

The present disclosure relates to an apparatus comprising a controller, an inverter, a load and a DC link. The DC link is coupled to the load and couplable to a power source. The load comprises an AC electrical component. The inverter is configured to provide an output voltage and an output current to the AC electrical component, the output voltage having an output frequency. The controller is configured to: evaluate a component startup criterion relating to whether the AC electrical component is performing a startup process; in response to a determination that the component startup criterion has been met, operate the inverter in a protected startup mode; and when operating the inverter in the protected startup mode, control the output frequency such that the output frequency increases with time until the output frequency reaches a predefined operating frequency.
