Abstract
A high voltage direct current (HVDC) power distribution system comprises at least one power bus; at least one load conductor; and a hybrid contactor for interconnecting the at least one power bus and the at least one load conductor and through which inductive energy passes upon disconnection of the at least one load conductor from the at least one power bus. A first portion of the inductive energy passes through the hybrid contactor as an arc. A second portion of the inductive energy passes through the hybrid contactor as resistively dissipated heat.
