Abstract
In accordance with aspects of the present invention, a magnetic secured transmission system is presented. A magnetic secure transmission (MST) system can include a full-bridge driver that includes four transistors configured to regulate current through a coil; and a driving controller coupled to drive the full-bridge driver at a high frequency. In some embodiments, the transistors in the full bridge regulator are driven with a high frequency pulsed-wave modulated (PWM) signal to control the current through the coil. A method of magnetic secured transmission (MST) of MST data according to some embodiments includes receiving the MST data; generating coil data in response to the MST data; driving transistors in a full bridge at a high frequency to drive current through a coil according to the coil data.
