“…Such magnetic sensors, integrated in regular CMOS technology, prove to be cost-effective and offer high performance [2]. The circuit comprises of two Hall Effect based current sensor with an open core magnetic concentrator for good reliability and repeatability [3]. An average value of output from two Hall Effect sensors is taken for Redundancy based plausibility checking as it provides a much higher potential in terms of detection time and precision [4] which is givento a comparator.…”

Now-a-days electrical vehicles are growing faster than the vehicles fuelled with conventional energy resources and are expected to replace conventional vehicles in near future,owing to its zilch emissions and environmental friendly. Albeit the electrical vehicles are contributing to the reduction in air and noise pollution, few technical issues have to be resolved for its improved performance. Currently electric vehicle is turned off automatically, for avoiding the shaft failure due to the twisting load acting on the shaft, while operator applies the accelerator pedal and brake pedal simultaneously. Hence, an attempt had been made to delay the system getting turned off by introducing a timer circuit in BSPD (Brake System Plausibility Device). The functioning of simplified BSPD with timer circuit was simulated using the Proteus software andthe outcome of the simulated results is presented in waveforms, which confirms the proper functioning of the circuit. A PCB for engaging the shutdown circuitwas also developed to control the electric vehicle’s powertrain. The hardware implementation of the simulated circuit had been carried out and the real time working of the circuit was verified.

“…This platform’s approach is based on the Finite Elements Method (FEM) [ 68 , 69 ], and it shares several modules. Several types of micro- and nanoscale devices have been designed with this platform [ 70 , 71 ]. In the specific case of Hall Amplifier [ 71 ], the required simulation models are the AC/DC module, the semiconductors module, and the Heat Transfer module.…”

A comprehensive review of the main existing devices, based on the classic and new related Hall Effects is hereby presented. The review is divided into sub-categories presenting existing macro-, micro-, nanoscales, and quantum-based components and circuitry applications. Since Hall Effect-based devices use current and magnetic field as an input and voltage as output. researchers and engineers looked for decades to take advantage and integrate these devices into tiny circuitry, aiming to enable new functions such as high-speed switches, in particular at the nanoscale technology. This review paper presents not only an historical overview of past endeavors, but also the remaining challenges to overcome. As part of these trials, one can mention complex design, fabrication, and characterization of smart nanoscale devices such as sensors and amplifiers, towards the next generations of circuitry and modules in nanotechnology. When compared to previous domain-limited text books, specialized technical manuals and focused scientific reviews, all published several decades ago, this up-to-date review paper presents important advantages and novelties: Large coverage of all domains and applications, clear orientation to the nanoscale dimensions, extended bibliography of almost one hundred fifty recent references, review of selected analytical models, summary tables and phenomena schematics. Moreover, the review includes a lateral examination of the integrated Hall Effect per sub-classification of subjects. Among others, the following sub-reviews are presented: Main existing macro/micro/nanoscale devices, materials and elements used for the fabrication, analytical models, numerical complementary models and tools used for simulations, and technological challenges to overcome in order to implement the effect in nanotechnology. Such an up-to-date review may serve the scientific community as a basis for novel research oriented to new nanoscale devices, modules, and Process Development Kit (PDK) markets.

“…The application of integrated-circuit sensors placed in the air gap of a magnetic core for the measurement of AC and DC voltages, currents, and magnetic flux density in electrical machines is constantly being developed [ 1 , 2 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. For AC and DC currents with a magnetic flux density, contact and contactless measurement, Hall-effect sensors, magnetoresistive current sensors, and coils (e.g., the Rogowski coils are only suitable for AC currents) [ 16 , 17 , 22 , 23 , 24 ] are commonly used. In cases of voltages up to 1 kV, with output separation, both magnetoresistive current sensors and Hall-effect sensors can be used after placing them in the air gap of a ferromagnetic core, and voltage measurement is carried out by using the current to measure magnetic flux in the measuring winding that is wound around the core [ 25 , 26 , 27 ].…”

“…Voltage transducers with both closed and open feedback loops are available on the market [ 4 ]. In order to amplify the measured voltage, current, or magnetic field, the Hall-effect sensor is placed in the core air gap [ 2 , 7 , 8 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. The magnetic flux density shape in the core and in the air gap depends on the electric and magnetic properties of the core and on the range of measured frequencies.…”

This paper presents the project proposal of a low-cost transducer with a Hall-effect sensor placed in a ferromagnetic core’s air gap, which enables the measurement of the distorted voltage instantaneous values without the feedback loop used for measurements in electrical machines. The presented transducer allows for electrical separation between the measured voltage and the voltage at the output. Moreover, the influences of frequency, additional resistance, and the reactance of the winding circuit on the voltage phase shift caused by winding inductance with ferrite core and amplitude are discussed. The result of simulating leakage inductance of measuring winding with ferrite core with an air gap is calculated using finite element analysis. Experimental investigations of the voltage phase shift angle and output voltage amplitude drop for the voltage transducers with an open feedback loop are carried out, taking into account the linear core magnetization characteristic.
