Overview of Automotive Silicon-based and SiC-Based Inverters:

Automotive inverters play a crucial role in electric vehicles (EVs) by converting direct current (DC) from the battery into alternating current (AC) to power the electric motor. Silicon-based and silicon carbide (SiC)-based inverters are two prominent types of inverters used in the automotive industry.

Silicon-based inverters have been widely used due to their established technology and relatively lower cost. They utilize silicon-based power semiconductors, such as insulated-gate bipolar transistors (IGBTs) or metal-oxide-semiconductor field-effect transistors (MOSFETs). These inverters provide reliable performance and are suitable for various EV applications.

On the other hand, SiC-based inverters employ silicon carbide power semiconductors, which offer superior electrical properties compared to silicon. SiC-based inverters enable higher power density, lower losses, and higher operating temperatures, leading to increased efficiency and improved overall performance of electric vehicles.
