Abstract
A ferrite module matrix driver circuit comprises a controller, a charging circuit, a plurality of ferrite modules arranged in the form of a matrix, a plurality of first switches driven by the controller, a plurality of second switches driven by the controller, and one or more comparators coupled to the charging circuit and the controller. Each switch in the first plurality of switches connects a respective column of said plurality of ferrite modules to the charging circuit. Each switch in the second plurality of switches connects a respective row of said plurality of ferrite modules to ground. And, after a specific voltage has been reached by the charging circuit, one of the comparators signals to the controller, which in turn selects a specific ferrite module to be polarized by driving one of the plurality of first switches and one of the plurality of second switches.
