Introduction

The high voltage, miniaturization, and lightweight trends in the field of new energy vehicle power are inevitable. Silicon carbide (SiC) technology provides us with endless new opportunities. In many fields seeking highly reliable power systems, SiC MOSFETs provide perfect solutions for diverse applications in various industries, including but not limited to applications that require robust operation in harsh environments. This article will take VBsemi Silicon Carbide MOSFET as an example to discuss its working principle and advantages in the field of high-power applications.

Advantages of Silicon Carbide MOSFET

Compared with traditional silicon MOSFETs, the new generation of silicon carbide MOSFETs has significantly reduced on-state resistance and switching losses, achieving higher operating frequencies. At the same time, its high-temperature characteristics greatly improve the stability of the device in high-temperature environments. The advantages of silicon carbide MOSFETs are mainly reflected in four aspects: high operating temperature, high blocking voltage, low loss, and fast switching speed.
