Infineon Technologies AG has announced the launch of 650 V CoolSiC Hybrid Discrete for Automotive.

The device, according to the company, contains a 50 A TRENCHSTOP 5 fast-switching IGBT and a CoolSiC Schottky diode to enable a cost-efficient performance boost as well as high reliability.

This combine constructs a perfect cost-performance trade-off for hard-switching topologies and supports high system integrity in addition to bi-directional charging.

Infineon says 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.

The integrated fast-switching 50 A IGBT enables MOSFET-like turn-off behavior outperforming pure silicon solutions.

As against regular silicon carbide MOSFETs, the plug-and-play solution for a fast time-to-market achieves 95 to 97 percent system efficiency at less cost.

Moreover, the CoolSiC Schottky diode supports reduced turn-on and recovery losses. When compared to pure silicon designs, the device is ideal for hard commutation with 30 percent lower losses.

Thanks to its low cooling requirements, the diode also provides an excellent cost-performance trade-off on the system level.

Xu Jinzhu, R&D Director of VMAX, said, “The partnership we have with Infineon is an essential cornerstone of our philosophy of consistently creating maximum value for our customers.”

Jinzhu added: “The CoolSiC Hybrid Discrete allows us to simplify driver design, accelerate product development, lower costs and increase system robustness. The integrated silicon carbide diodes without reverse recovery charge further optimize the EMC characteristics of the system.

This results in greater performance benefits and a better price/performance ratio in topologies such as totem-pole PFC and DAB.”

OBC Supplier

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

Jürgen Spänkuch, Vice President for Automotive High Power Discretes and Chips at Infineon said that they are very happy about this close partnership and the great collaboration with VMAX. This project further highlights our strong position in the on-board charger application, he added.
