This paper studies the effect of various mitigation loop configurations namely: single horizontal mitigation loop (two conductors), two separate horizontal mitigation loops (four conductors) and single vertical mitigation loop (two conductors), on the magnetic field produced by 220 kV double-circuit overhead transmission line. Also, in this paper a further reduction in the magnetic field is ach...

The paper presents operational characteristics of a small induction motor with the stator core made of amorphous laminations, supplied from mains or frequency inverter at 100 and 200 Hz. Calculations were performed using field-circuit and equivalent circuit approaches taking account of non-linearity and additional losses both in the core and in the windings. Data for mechanical losses, magnetis...

An inertia electromagnetic actuator capable of adjusting natural frequency is designed in this paper. There are two procedures in the design of electromagnetic actuator: magnetic circuit design and stiffness conditioning design. ANSOFT software is used to simulate the magnetic circuit during the magnetic circuit design and optimize the design of the actuator. In order to adjust the natural freq...

A magnetic field sensor was developed using the asymmetric giant magnetoimpedance (AGMI) effect. Amorphous ferromagnetic (Fe0.06Co0.94)72.5Si12.5B15 wires were used in this study. The 2-cm-long wire showed an approximately 88% effect, and 7-cm-long 197% When two micromagnets placed 1 cm from ends of wire, a distortion peak shapes GMI curve observed, asymmetry created by micromagnets. 148% AGMI ...

This paper shows, for the first time, a complete magnetic field sensing system including a Lorentz-force sensor operating at a frequency slightly lower than the mechanical resonance coupled to an integrated circuit for sensing and driving the device. Working out of resonance, the trade-off between maximum sensing bandwidth and minimum detectable magnetic field is overwhelmed, allowing to improv...

Permanent magnet machines (PMs) equipped with fractional slot concentrated windings (FSCWs) have been preferably proposed for electric vehicle (EV) applications. Moreover, integrated on-board battery chargers (OBCs), which employ the powertrain elements in charging process, promote zero-emission future envisaged transportation through transition to EVs. Based on available literature, employed m...

For certain applications, it is critical to minimize variations in the (throughput) timing between trigger and the output pulse of a magnetic modulator. A circuit is described in this paper that maintains a relatively constant delay over a large operating voltage range (600–1150 V) and temperature range (25 C–65 C) range. The circuit operates by sampling the charging voltage and magnetic switch...
