A Step Forward to Miniaturization for Current Sensing in Power Conversion Systems Modern power conversion systems must simultaneously become more efficient, smaller and cheaper than previous generation. With this in mind, the Swiss company LEM, global leader in current and

As power electronics systems get smaller, LEM is introducing three new families of compact open-loop current sensors which measure higher currents than earlier sensors of the same size, or similar currents with smaller size. Excellent performance is obtained using a

INTRODUÇÃO Uma aplicação muito frequente na indústria de sensores magneto-resistivos é o sensoriamento da intensidade da corrente que circula num circuito. Esse sensoriamento serve para realimentar os circuitos de controle PWM que determinam a velocidade e potência de motores, acionamento
