Many info like accuracy, current, delivery systems, and range are described inside this paper. Inside the paper we can get description regarding current measurement, sensors, and integrator.
The paper contains things such as ac current sensors, measurement, and hall effect. Here are taken from the paper:
Current sensors are essential components in many power delivery systems such as ac-dc and isolated dc-dc switch mode power supplies (SMPS), motor control and electronic lighting. As power supply manufacturers strive to increase the power density and reliability of their products, “green” energy mandates are simultaneously driving the need to increase energy efficiency. System designers are consequently demanding smaller, more efficient and higher performing current sensors.
Furthermore, the paper explains information about efficiency, sensor, and current sensors.
