Abstract
An LED driver circuit includes a primary circuit and a circuit electrically isolated from the primary circuit, a transformer having a primary winding configured to receive power from an alternating current source and to generate power in a first secondary winding configured to provide power to the electrically isolated circuit, and to generate power in a second secondary winding configured to provide power to the primary circuit, and a conductor connected to an end of the first secondary winding and configured to connect a winding driver signal to the first secondary winding to generate power in the second secondary winding.
