“…Dealing with the field of electrical drives, electrical machines tend to suffer the high voltage slew-rate imposed by the converter resulting in premature aging of the insulations and the excitement of parasitic capacitances that can lead to impulsive common mode currents. High voltage slew rate combined with the use of long cables can lead to significant over voltages at the end of the cables [6]- [7]. For this reason, it is important find a compromise between increasing the dv/dt to reduce the switching losses and mitigating the problems discussed above.…”

SiC power MOSFETs are an advancement in the power electronics technology today available on the market. Respect to Si-based power devices, they offer potential for higher operating temperatures, higher breakdown voltage with low onstate resistance, and lower switching losses permitting much higher switching frequencies. To date, the attempts to apply the SiC power devices to the field of AC drives are relented by the high price of such new devices and by the challenges related to electromagnetic compatibility and reliability. A new test rig is proposed, built for comprehensively testing SiC power MOSFET modules in real operating conditions, using off-the-shelf hardware. The presented results focus on the evaluation of onresistance as a function of drain current and junction temperature, and on dv/dt evaluation as a function of external gate resistance. Different modules are tested, custom realized using SiC MOSFET dies by two leading manufacturers. Finally, a new methodology for on-line estimation of the devices junction temperature is presented.

As we know, submersible motor which works underground is powered by long cable. This will lead to a series of problems, such as overvoltage and high-frequency oscillation damping. To facilitate the effective suppression of motor terminal overvoltage, transmission line theory and distributed parameter thought are adopted into the motor terminal voltage analysis. Based on submersible motor system modeling, a specific function of factors that affect motor terminal overvoltage including cable length, PWM pulse rising time and terminal reflection coefficient is given and verified by simulation. Moreover, this article puts forward a novel method of designing LR parallel filter, which only needs the natural oscillation frequency of long cable without complex design steps. Simulation results show that passive filter design method used in this paper is simple and restrains terminal overvoltage within 20%.I.

“…[1], [2], [3], [4], [5], [6]. These EMC related problems are exacerbated in Smart Grids due to the necessity of the connection of high emission PEIs with susceptible smart metering equipment, the aggregation of interference generated by a group of PEIs and the flow of interference in extensive circuits comprising low voltage (LV) and medium voltage (MV) grids.…”
