ABSTRACT:
The present invention is directed to a transient suppressor, a method of suppressing a peak voltage associated with a rectifier, and a power converter employing the same. In one embodiment, the transient suppressor includes a saturable reactor circuit interposed between a rectifier and a transformer winding. The transient suppressor also includes a RC circuit, coupled between the rectifier and the saturable reactor circuit and across the transformer winding, configured to cooperate with the saturable reactor circuit to suppress a peak voltage associated with the rectifier.
