DynamicParameterAllocation It is functionally given that inverters must be significantly reduced in output current at low rotational frequencies. Lower PWM switching frequencies due to reduced switching losses in turn enable higher currents. With the DynamicParameterAllocation module, we make a clear use of these correlations, especially for traction. We set the optimum PWM frequency with associated parameters for each operating point in speed and torque. Application areas: Mainly traction drives, but also suitable for winches and other applications. Features and benefits: · The entire map is 2-dimensionally adaptable to the dedicated application. · The switchover to each operating point takes place in real time under 1 ms and can therefore also follow dynamic processes without any problems. · Switching takes place without relevant influence on torque and speed of the control system. · In real applications, up to 50% higher starting torques are often achieved from standstill. Related hardware: All VECTOPOWER Inverters Series2 and Series3. #traction #speed #frequency Es ist funktional gegeben, dass Inverter bei niedrigen Drehfrequenzen im Ausgabestrom deutlich reduziert werden müssen. Geringere PWM-Schaltfrequenzen durch reduzierte Schaltverluste ermöglichen wiederum höhere Ströme. Mit dem Modul DynamicParameterAllocation machen wir aus diesen Zusammenhängen einen deutlichen Nutzen insbesondere für die Traktion. Wir stellen für jeden Betriebspunkt in Drehzahl und Drehmoment die optimale PWM-Frequenz mit zugehörigen Parametern ein. Anwendungsbereiche: Vor allem Traktionsantriebe, aber auch geeignet für Winden und andere Anwendungen. Merkmale und Vorteile: · Das gesamte Kennfeld ist 2-dimensional anpassbar auf die jeweilige Anwendung. · Die Umschaltung auf jeden Betriebspunkt erfolgt in Echtzeit unter 1 ms und kann damit auch dynamischen Vorgängen problemlos folgen. · Die Umschaltung erfolgt ohne relevanten Einfluss auf Drehmoment und Drehzahl der Regelung. · In realen Anwendungen werden oft bis zu 50% höhere Anfahrdrehmomente aus dem Stillstand erreicht.

Why SiC-MOSFETs are suitable for #EV traction inverters compared to Si-IGBT : 1. SiC-MOSFETs have high breakdown voltage with low switching losses. Hence, there is an enhancement in efficiency by 1.4% - 4.4% 2. Critical Electric Field 'Ecrit' value of SiC is 7 times that of Si Ecrit . Hence thinner devices can be made at the same breakdown voltage. 3. Planer SiC-MOSFETs are suitable for high frequency applications due to low switching losses. 4. Overall, wide band gap semiconductor devices are more efficient than their Si-based counterpart due to significantly less leakage current. 5. Maximum junction temperature of Si-based device is around 150°C while SiC-MOSFETs can operate at temperatures up to 200°C . The ability of SiC devices to withstand high temperature and switch faster with low switching losses directly result in improved thermal management and decrease in the size of heat sinks as well as cooling systems. #Inverter #TeslaMotors #Rivian #PowerElectronics
