Temperature-compensated shunt current measurement

摘要: A current sensor includes a shunt and at least one resistant element. The conveys an electric current, has resistance which varies with the shunt's temperature. element, that its own temperature, is electrically connected between output terminal of sensor. At portion element in thermal contact predetermined location on shunt, so element's accordance may be to amplifier whose gain variation causes change gain, compensates for changes due change's In some embodiments, second terminal.
