“…In the case of a single stage current transformer, the high cut-off frequency can be evaluated by (5). Compared to (5), (7) shows that the upper frequency limit is increased for the two-stage ACT, the frequency ratio is C. Modeling of the ACT² In this section the determination of the ACT 2 model is proposed. The components values that ensure a trough cancellation of the transfer function, given by the Hall generator stage and the two-stage current transformer, are determined.…”

This paper is focused on the design and the realization of two high current probes (up to 100 A) whose bandwidths range from DC to 50 MHz. These performances have been met by the association of an active Hall sensor and a passive current transformer. This association will be named "active current transformer" (ACT). It will be shown that it has better frequency performances than the classical closed-loop current transducer, usually used for high current measurements but frequency limited. The EMI issues, due to the sensor electrical environment are respected thanks to the shielded structure and special inner arrangements of the Hall sensors. Because of its large bandwidth, its large current ranging and its EMI ruggedness, this current probe is well matched to power electronics measurements.

“…Wireless energy transfer using magnetically coupled inductors has a wide range of applications, such as contactless battery chargers, implementable biomedical devices, cordless electric toothbrushes, and mobile telephones [57][58][59][60][61][62][63][64][65][66][67][68][69][70]. This method of energy transfer is also preferred in hazardous applications, such as mining due to elimination of sparks and underwater due to elimination of electrical shocks.…”

Abstract-A theoretical study and a simulation method are proposed for superparamagnetic current sensors implementing a uniformly wound toroidal core topology. So as to be easy to implement, this sensor topology can be made flexible thanks to the use of a core made up of a superparamagnetic powder embedded in a flexible plastic matrix. The measurement of DC and AC currents is possible provided that a sinusoidal magnetic field excitation is applied to the superparamagnetic transducer. An analytical model is proposed for computing the sensor output signal and we demonstrate that when the detection of the component at the second order harmonic of the excitation frequency is used, the measurement is independent of the conductor position in a given current range. For simulating the dynamic response of the sensor, we propose to combine the analytical model, or a finite elements model, with a time-discretization method. Furthermore, simulations are carried out considering a ring shaped sensor and the real magnetization characteristics of a superparamagnetic material. Simulations are provided over the [−10 kA 10 kA] range and for various amplitudes of the excitation signal. The results obtained with the analytical model, which is computationally efficient, are within 4% to 12.7% from the numerical results.
