Abstract
Systems and methods for current sensing are described. For example, a system may include a transformer including a winding that connects a first tap and a second tap; a circuit board; a first trace on a layer of the circuit board, wherein the first trace connects the first tap to a rectifier; a coil including one or more turns of trace on the layer of the circuit board, adjacent to the first trace; and a measurement circuit configured to estimate current flowing in the first trace based on voltage across the coil.
