Abstract
A three-phase power supply circuit is provided. The power supply circuit includes three LLC resonant voltage convertors, three step-down transformers, and a bridge rectifier. Each step-down transformer includes a primary and secondary coil, and each primary and secondary coil has a first node and a second node. Each step-down transformer is electrically coupled with one of the three LLC resonant voltage convertors by the first and second nodes of the primary coils. The bridge rectifier is electrically coupled with the first node of the secondary coil of each of the three step-down transformers. The second nodes of the secondary coils of each of the three step-down transformers are electrically coupled together.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
