(H)EV – Haupt-Wechselrichter
Im Elektroantrieb ist der Haupt-Wechselrichter für die Steuerung des Elektromotors zuständig. Als eines der wichtigsten Bauteile in einem Auto bestimmt es das Fahrverhalten und trägt entscheidend zum Gesamtwirkungsgrad des Fahrzeugs bei. Zusätzlich nimmt der Haupt-Wechselrichter Energie auf, die durch regenerative Bremsen freigesetzt wird, und speist sie wieder in die Batterie ein. Das Ergebnis: Die Reichweite eines Fahrzeugs steht in direktem Verhältnis zum Wirkungsgrad seines Haupt-Wechselrichters.
Infineon bietet Ihnen für alle Haupt-Wechselrichter-Anwendungen ein breit gefächertes Portfolio und ein außerordentliches Maß an Anwendungs- und Systemkompetenz. Unser Produktsortiment spiegelt genau das wider, wonach Sie hinsichtlich Wirkungsgrad und Kosten suchen. Außerdem bieten wir Ihnen gerne fachliche Unterstützung bei jedweden Fragen.

Technology choice (Si and SiC) in EV traction inverter systems
SiC-based power electronics for EV traction motor inverters are accelerating rapidly. Given the WLTP mission profile, where partial load dominates, SiC demonstrates an efficiency gain of approximately 4% over its silicon counterpart. It is most likely that Si and SiC will co-exist as both have their unique benefits. A Si/SiC hybrid solution is often considered for traction and secondary inverters where SiC is applied for rear-wheel drive, aiming to extend the range, whereas silicon is used in front-wheel drive to allow cost optimization.
