Current Sensing For Automotive Electronics -- A Survey, Asha Patel, Mehdi Ferdowsi
Current Sensing For Automotive Electronics -- A Survey, Asha Patel, Mehdi Ferdowsi
Electrical and Computer Engineering Faculty Research & Creative Works
Current sensing is widely used in power electronic applications such as dc-dc power converters and adjustable-speed motor drives. Such power converters are the basic building blocks of drivetrains in electric, hybrid, and plug-in hybrid electric vehicles. The performance and control of such vehicles depend on the accuracy, bandwidth, and efficiency of its sensors. Various current-sensing techniques based on different physical effects such as Faraday's induction law, Ohm's law, Lorentz force law, the magnetoresistance effect, and the magnetic saturation effect are described in this paper. Each technique is reviewed and examined. The current measurement methods are compared and analyzed based on …

Multi-input power electronic converters have been gaining popularity in applications such as renewable energy sources and hybrid electric vehicles due to their reduced component count. In this paper, a new control method is introduced and successfully applied to a double-input buckboost converter to adjust the power supplied by each one of the sources. The control scheme is based on controlling the offset time between the switching commands while switching frequency is kept constant. Theoretically, it is proved that the offset time between the switch commands has a direct impact on the amount of current drawn from each source. The proposed …
