Abstract:
Systems, methods, and apparatuses are provided in which power control relay switches may be configured to switch at or near a predetermined time during an AC cycle and/or that are configured to control a velocity of an armature of the relay switch during switching. An input power source may provide alternating current (AC) power and a voltage or current level of the AC power may be sensed. A relay controller may switch the relay switch based on a time at which the voltage or current is at or near a zero-crossing. The relay controller may be configured to close the relay switch based on when a voltage of the power input is at a zero-crossing, and is configured to open the relay switch based on when a current of the power input is at a zero-crossing.
