Hall Effect current sensors can be used to measure DC current, AC current, and even pulsed current waveforms. Transducers are designed to sense the primary current flowing through them and provide an output signal that is proportional to the measured primary current. In an open-loop type sensor, the output is a scaled (polarity and magnitude) voltage level. In a closed-loop type sensor, the output is a scaled (polarity and magnitude) current level. Applications for Hall Effect current transducers include battery management circuits, battery chargers, arc welders, uninterruptible power supplies (UPS), and inverters.
