Abstract

The electrical relay in an essential part of the Smart Grid, Electrical Vehicle (EV) and LED lightning system. For these reasons, research of electrical relay is actively underway. In this paper, analyze of the relationship between the bouncing of relay contact and magnetic flux of permanent magnet. Experiment result, changes the bouncing numbers depending on the magnetic flux of the latching relay. And find the value of the magnetic flux that occurs to minimize the bouncing of the contacts. In additions, by the increasing the magnetic flux, unconditional bounce is not reduced. The bouncing number of latching relay is less than expected the armature relay for present results. Further experiments are need to prove it, bouncing on the armature relays.
