Abstract
Arc suppression of a dc energized contactor is presented. A circuit is developed to operate the contactor at zero voltage crossing for contact closure and at zero current crossing for contact opening under inductive load. A self-learning feature of contactor characteristics is also provided in the circuit such that the device can be adaptable to any dc energized contactor without discrimination.
