Abstract
A particulate filter assembly includes an electrode assembly, a particulate filter positioned in an electrode gap defined between two electrodes of the electrode assembly, a power supply electrically coupled to the electrode assembly, and a controller for controlling operation of the power supply to apply a regenerate-filter signal to the electrode assembly to oxidize particulates collected by the particulate filter. An associated method of regenerating the particulate filter is disclosed.
