SiC power components are not unfamiliar to everyone, but many fans respond with some technical points. ROHM Jun specializes in handling related knowledge, from the most basic introduction to the ultimate use of methods, whether you are white or "old driver", you can also learn the new situation.
Today, ROHM Jun introduces the “full SiC power module†that consists entirely of SiC power components. This article wants to let everyone know what kind of product the full SiC power module is and what models are available. Then plan to introduce its characteristics, performance, application cases and use methods.
What is a full SiC power module
ROHM is the first in the world to mass-produce "all-SiC power modules" equipped with SiC-MOSFETs and SiC-SBD manufactured by Roma. Compared with previous Si-IGBT power modules, "full SiC" power modules can be switched at high speeds and significantly reduce losses. In this regard, the characteristics and performance of the SiC-SBD and SiC-MOSFETs previously described can be easily understood.
At present, all SiC power modules that Rom is mass producing are two-in-one modules, including half-bridge type and step-up chopper type.
In addition, there are product types that carry NTC thermistors in the lineup.
The following is a summary of the existing product lineup and major specifications. The product range of 1200 V withstand voltage 80A to 600A is complete, and two models of 400A and 600A have recently been developed. The product lineup has a wide range of products covering 100 A to 600 A of the main rated current in the IGBT module market.
Progressive full SiC power module
The latest all-SiC power modules use the latest SiC-MOSFETs (ie, third-generation trench structure SiC-MOSFETs) to further reduce losses. The following is an example.
Key point small blackboard:
・All SiC power modules consist of ROHM's own SiC-MOSFETs and SiC-SBD.
・Compared with Si-IGBT power modules, "full SiC" power modules can switch at high speed and reduce losses significantly.
* Full SiC power modules are evolving, and the latest products are equipped with the latest third-generation SiC-MOSFETs.
