Design Analog Discrete Power Device Qorvo

Qorvo Low RDS(on) SiC FETs Deliver Unparalleled Efficiency

AC Propulsion develops electric vehicle technology and provides products and engineering services to automotive and other clients worldwide. When developing a second-generation power module for its own low-cost drive unit inverter, AC Propulsion needed a power semiconductor that would deliver 2-5% higher switching efficiency compared to existing IGBT-based designs. did.

solution

A 3-phase AC traction inverter for EVs, designed by AC Propulsion using Qorvo UF3SC120009K4S, 1200V, 9mohm SiC FETs, offers improved efficiency over competing SiC devices. It is also packaged in the common TO-247 package, making it a more efficient and cost-effective drop-in replacement.

merit

With a low RDS(on) of 9mΩ, new high-performance power module designs use fewer discrete components, saving system cost and space. Its efficiency allows you to use a self-contained heatsink while still delivering great performance.

Using Qorvo FETs and IGBTs improves drive cycle efficiency by 3%-5%. This means that the range could be increased and the battery size could be reduced.
