Abstract
An apparatus and method for improved current shunt sensing in an electrical system, such as a renewable energy electrical system, is disclosed. A current shunt according to aspects of the present disclosure includes a conductive portion that is placed in series with an electrical system The current shunt includes a sensing element that is used to measure the voltage across the conductive portion of the current shunt. The sensing element has an increased width relative to the width of the conductive portion of the shunt. The increased width of the sensing element provides for improved current shunt sensing that results in more accurate voltage (and thus current) measurements across a wide range of frequencies.
