New 650 V CoolSiC Hybrid Discrete for Automotive Enables Fast Switching On-Board Charger Applications

Infineon Technologies launched the 650 V CoolSiC Hybrid Discrete for Automotive

The device contains a 50 A TRENCHSTOP 5 fast-switching IGBT and a CoolSiC Schottky diode. This combination is designed to build a cost-performance trade-off for hard-switching topologies and support system integrity in addition to bi-directional charging. This makes the device ideal for fast switching automotive applications such as On-Board Chargers (OBC), Power Factor Correction (PFC), DC-DC, and DC-AC converters.

Per the company, the integrated fast-switching 50 A IGBT enables MOSFET-like turn-off behavior outperforming pure silicon solutions. In contrast to regular silicon carbide MOSFETs, the plug-and-play solution for ideal time-to-market achieves 95 to 97 percent system efficiency at a lower cost level. Furthermore, the CoolSiC Schottky diode supports reduced turn-on and recovery losses. In comparison to pure silicon designs, the device is ideal for hard commutation with 30 percent lower losses. With its low cooling requirements, the diode also provides a suitable cost-performance trade-off on the system level.

Shenzhen VMAXPower is a OBC supplier in China, focusing on the development of automotive power electronics and providing customers with reliable OBCs and DC-DC converters. VMAX uses Infineon’s latest CoolSiC Hybrid Discrete in their next-generation OBC/DC-DC system.

The CoolSiC Hybrid Discrete for Automotive is now available.
