ABSTRACT:
An apparatus and method used to charge a self powered gate driver system. The apparatus may include a current loop for inducing a current in a coil. A bridge rectifier may rectify the current induced in the coil and charge a capacitor used to power a driver in a self powered gate driver system. The current loop and coil may be separated by a dielectric to prevent current from passing between the self powered gate driver system and the current loop. The current loop may couple to a line voltage transformer to drive an alternating current through the current loop. In certain embodiments, a single current loop and transformer may charge a plurality of self powered gate driver systems.
