“…In terms of TSEPs v th and v gp , they are unlikely for the online extraction because of their low sensitivity (About few millivolts per degree [11]) and sensitive sensing circuit requirements. Additional components are needed to convert dynamic dv/dt and di/dt to an observable signal, like RC circuitry or a PCB Rogowski coil, which affect IGBT switching characteristics [17][18]. Particularly, the turn-on current of IGBT intertwined with the reverse recovery current of corresponding diode in the commutation circuits, thus di/dt (max) during the turn-on interval may not reflect the IGBT junction temperature accurately.…”

Abstract -Thermo-sensitive electrical parameter (TSEP) approaches are widely employed in the junction temperature extraction and prediction of power semiconductor devices. In this paper, the turn-off delay time is explored as an indicator of a TSEP to extract the junction temperature from high power insulated gate bipolar transistor (IGBT) modules. The parasitic inductor L eE between the Kelvin and power emitter terminals of an IGBT module is utilized to extract the turn-off delay time. Furthermore, the monotonic dependence between the junction temperature and turn-off delay time is investigated. The beginning and end point of the turn-off delay time can be determined by monitoring the induced voltage v eE across the inductor L eE . A dynamic switching characteristic test platform for high power IGBT modules is used to experimentally verify the theoretical analysis. The experimental results show that the dependency between IGBT junction temperature and turn-off delay time is near linear. It is established that the turn-off delay time is a viable TSEP with good linearity, fixed sensitivity and offers non-destruction on-line IGBT junction temperature extraction.Index Terms -Thermo-sensitive electrical parameter, high power IGBTs, on-line junction temperature extraction, turn-off delay time.

“…We create the model of the current bar by segmenting analytic curves, which we covered with a thickness and width in order to obtain a 3-D model. The fourth basic element is the PLC coupling element, the Rogowski coil, as illustrated in Fig 4. Usually, Rogowski coils are used as measurement elements for alternating current in a conductor [32]- [34], but Rogowski coils can be also used as PLC coupling elements [15], [35]. The most important advantage is that Rogowski coils are air-cored, as a result of which saturation effects cannot occur.…”

A model of the transmission channel is essential for designing a power-line communication (PLC) system for a lithium-ion battery pack in electric and hybrid vehicles. Currently, measurements of lithium-ion batteries have to be performed by specially trained staff in safety chambers, because they might cause severe safety problems. A simulation model of the battery would therefore highly facilitate the analysis of different battery packs. Our approach is to extend an existing circuitbased model of the power-line channel with a 3-D electromagnetic (EM) model. The 3-D EM model is well capable of describing the inner environment of the battery pack as well as PLC coupling elements, which is necessary because power lines can also act as antennas. On the other hand, a fully detailed 3-D EM model cannot be simulated within a reasonable period of time. This article gives essential insights into future PLC systems for battery packs in order to ensure safe usage of electric and hybrid cars for the user and the environment.

“…With the rapid development of smart grid and widely launch of intelligent substations, the shift to digitization in the power system made present-day metering and protection devices not need large power drive any more. Rogowski coils applied in current measurement in intelligent substations adapt to the development tendency and they are in extensive application at present stage [11].…”

Abstract. The principles of the active electronic current transformer (ECT) are introduced, and the mechanism of how a proximity magnetic field can influence the measuring of errors is analyzed from the perspective of the sensor section of the ECT. The impacts on active ECTs created by three-phase proximity magnetic field with invariable distance and variable distance are simulated and analyzed. The theory and simulated analysis indicate that the active ECTs are sensitive to proximity magnetic field under certain conditions. According to simulated analysis, a product structural design and the location of transformers at substation sites are suggested for manufacturers and administration of power supply, respectively.
