  • Controlling relay actuation using load current
    Patent number: 9887053
    Abstract: In some aspects, a relay control device includes a processor and a timer. The processor is electrically connectable to a relay that controls current flow to a load device. The processor causes the relay to be actuated at a first point in time so that a current flows to the load device. The processor determines an actuation duration for the relay from a measurement of the load current that is obtained with a current sense component. The processor determines a frequency of an input voltage or current from the measured load current. The processor synchronizes the timer with this frequency and identifies a zero-crossing point for a second load current based on the synchronized timer. The processor subsequently causes the relay to be actuated at a time that is offset from the zero-crossing point by the actuation duration.
