Abstract

본 발명은 릴레이 제어방법에 관한 것으로서, 릴레이 접점을 크로스할때 전류가 가장 많이 흐르는 지점에서 릴레이를 크로스 하므로서 발생되는 릴레이 접점의 손상을 제거하도록 한 것으로서, 릴레이를 크로싱할 때 부하에서 전류의 변화에 의한 전자기파가 이 전자기파는 마이콤의 고임피던스 포트에 유기되고 이것을 피드백 받아 전류가 가장 적게 흐르는 지점에서 릴레이를 크로스하여 릴레이 수명을 높이고 공진음을 제거하도록 한 것이다.The present invention relates to a relay control method, which is to remove the damage of the relay contact generated by crossing the relay at the point where the most current flows when crossing the relay contact, and to change the current at the load when the relay is crossed. Electromagnetic waves are induced in the high-impedance port of the microcomputer and fed back to cross the relay at the point where the current flows the least to increase relay life and eliminate resonance noise.
