TRANSFORMER POSITION SENSOR WITH SHORTED COIL

摘要

A transformer position sensor includes a primary coil, a secondary coil, and an electrically shorted coil. The primary coil is adapted to receive an excitation signal and is configured, upon receipt of the excitation signal, to generate a primary magnetic flux. The secondary coil is inductively coupled to the primary coil upon electrical excitation of the primary coil, and includes a plurality of differentially wound coils. The electrically shorted coil is inductively coupled to receive at least a portion of the primary magnetic flux generated by the primary coil. The electrically shorted coil is configured, upon receipt of at least a portion of the primary magnetic flux, to generate a magnetic flux that opposes the primary magnetic flux.
