Abstract
Systems and methods for deactivating an Electronic Article Surveillance ('EAS') tag. The methods comprising: using an AC drive signal to charge an energy storage component of the tag deactivator; selectively actuating a switch so that a closed circuit is formed between the energy storage component and at least one deactivation coil of the tag deactivator; generating a tag deactivation field to deactivate the EAS tag by energizing the at least one deactivation coil with current supplied from the energy storage component; and using a step down transformer, disposed between the energy storage component and the at least one deactivation coil, to decrease a frequency of a decaying coil current waveform representing a current flowing through the at least one deactivation coil.
