Abstract
A circuit and method for automatic rectification in a converter. The circuit is arranged in parallel to the secondary side of a transformer and acts as a free wheeling diode. The method uses a blocking signal from a current transformer to block the circuit when a current caused by a change in voltage on the primary side of the converter flows through the current transformer.
