Silicon Carbide (SiC) MOSFETs

Our SiC MOSFETs are designed to be fast and rugged and include system benefits from high efficiency to reduced system size and cost. MOSFETs are metal–oxide–semiconductor field-effect transistors with insulated gates. These silicon carbide MOSFETs have a higher blocking voltage and higher thermal conductivity than silicon MOSFETs, despite having similar design elements. SiC power devices also have a lower state resistance and 10 times the breakdown strength of regular silicon. In general, Systems with SiC MOSFETs have better performance and increased efficiency when compared to MOSFETs made with silicon material.

There are many advantages to choosing SiC MOSFETs over silicon MOSFETs, such as higher switching frequencies. High-temperature development is also not a concern when using SiC MOSFET modules because these devices can operate efficiently even in high heat. Additionally, with SiC MOSFETs, you benefit from a more compact product size because all components (inductors, filters, etc.) are smaller.

Silicon Carbide (SiC) Modules

SiC Modules contain SiC MOSFETs and SiC diodes. The boost modules are used in the DC-DC stages of solar inverters. These modules use SiC MOSFETs and SiC diodes with voltage ratings of 1200V.

A Silicon Carbide (SiC) Module is a power module that operates with Silicon Carbide semiconductors for its switch. The purpose of a SiC power module is the transformation of electrical power through switches to improve system efficiency.

The primary function of SiC Modules is to transform electrical power. Silicon Carbide offers an advantage over silicon because, with less resistance to move away from the source (due to increased efficiency), SiC devices can operate at a higher switching frequency. A SiC based system is also more compact and lightweight than a silicon solution, allowing for smaller designs. Therefore, SiC devices are the ideal solution for situations where you want to increase efficiency and improve your thermal management.
