Abstract
A planar transformer including a Faraday shield between primary and secondary windings. The Faraday shield is a conductive layer having low conductivity areas. The low conductivity areas may be almost any pattern. The Faraday shield and the windings of the planar transformer formed on a circuit board. A voltage source such as ground is connected to the Faraday shield.
