Abstract:
1. A control device for switching power either “on” and “off” from an AC power source to a load, comprising: a storage device for storing a charge, wherein storage device powers the control device at times; a power stealing block for stealing charge from an AC power source and for storing the stolen charge on the storage device; a first switch for diverting electrical current from the AC power source to the power stealing block; and a control block coupled to the first switch, the control block monitoring a measure related to an AC voltage that is currently being supplied by the AC power source, and if the measure related to the AC voltage that is currently being supplied by the AC power source is less than a threshold value, the control block switching the first switch to a diversion state that divert current from the AC power source away from the load and to the power stealing block, and if the measure related to the AC voltage that is currently being supplied by the AC power source is greater than the threshold value, the control block switching the first switch to a non-diversion state that does not divert current from the AC power source away from the load and to the power stealing block.
