SYSTEMS AND METHODS FOR PROVIDING OPEN ARC ENERGY NORMALIZATION

A method may include receiving a command to move one or more armatures configured to move between a first position that electrically couples one or more first movable contacts to one or more second contacts and a second position that electrically uncouples the one or more first movable contacts from...

Zusammenfassung:A method may include receiving a command to move one or more armatures configured to move between a first position that electrically couples one or more first movable contacts to one or more second contacts and a second position that electrically uncouples the one or more first movable contacts from the one or more second contacts. The method may also include determining an operating frequency of the system, dynamically determining an open-before-zero target point associated with the operating frequency, and transmitting a command to the switching device to move the one or more armatures from the first position to the second position at the open-before-zero target point to normalize the arc energy over the operating frequency range.
