Patent ID: 7724549

Claim:
A device for conditioning power delivered to operate a motor comprising: a sealed housing having at least one input terminal extending through the housing and configured to receive an input power and at least one output terminal extending through the housing and configured to deliver an output power conditioned to power a motor coupled to the output terminal; a filter arranged in the housing and having an input configured to receive the input power from the input terminal, wherein the filter is further configured to suppress voltage changes in the input power and deliver a filtered power to an output of the filter; a transformer arranged in the housing and having an input configured to receive the filtered power from the output of the filter, wherein the transformer is at least configured to electrically isolate the input terminal from the output terminal and deliver a conditioned power from an output of the transformer to the output terminal to power the motor coupled to the output terminal; and a shared magnetic core extending through the filter and the transformer, the shared magnetic core including at least one gap formed in a portion of the core located within the filter.
