Current Measurement In Power Electronic And Motor Drive Applications - A Comprehensive Study, Asha Patel

Masters Theses

"Current measurement has many applications in power electronics and motor drives. Current measurement is used for control, protection, monitoring, and power management purposes. Parameters such as low cost, accuracy, high current measurement, isolation needs, broad frequency bandwidth, linearity and stability with temperature variations, high immunity to dv/dt, low realization effort, fast response time, and compatibility with integration process are required to ensure high performance of current sensors. Various current sensing techniques based on different physical effects such as Faraday's induction law, Ohm's law, Lorentz force law, magneto-resistance effect, and magnetic saturation are studied in this thesis. Review and examination of …
