Abstract
A DC offset voltage in an AC input voltage to a transformer and associated saturation current are eliminated by the placement of an anti-parallel diode pair circuit in series between a source of the AC input voltage and a primary winding of the transformer. The anti-parallel diode pair circuit has an input coupled to an output by parallel connected oppositely biased branch diode circuits. Each branch diode circuit has at least one diode where the diode of one such branch diode circuit is biased in one direction and the diode of the other such branch diode circuit is biased in an opposite direction and each branch diode circuit has the same number of diodes as the other branch diode circuit.

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.
