  • Systems and methods for delaying actuation of a relay
    Patent number: 9224561
    Abstract: A system includes a relay, an actuation circuit, and an actuation delay circuit. The relay is coupled to a source of an input voltage or current waveform. The relay includes an actuation coil. The actuation circuit detects a peak or valley of a rectified voltage ripple waveform. The rectified voltage ripple waveform is generated from the input voltage or current waveform. The actuation circuit also causes an actuation voltage to be provided to the actuation coil. The actuation delay circuit delays the actuation circuit from providing the actuation voltage. The actuation delay circuit is configured based on the peak or valley of the rectified voltage ripple waveform. The actuation delay generated by the actuation delay circuit causes the relay to begin allowing current to flow to a load device at a time coincident with a zero-crossing time value of the input voltage or current waveform.
