ON Semiconductor introduces new power modules for high-voltage EV inverters

ON Semiconductor has released the first two devices within its new VE-Trac family of power modules for high-voltage automotive traction inverters. Future devices in the VE-Trac family will include discrete power devices, isolated gate drivers, and wide bandgap (WBG) devices. The company says its first two devices are ideally suited for use in the main traction inverters of EVs, PHEVs and hybrids.

ON Semiconductor is introducing two different inverter platforms within the VE-Trac family: VE-Trac Dual and VE-Trac Direct.

VE-Trac Dual will be a collection of Dual Side Cool (DSC) half-bridge modules that are stackable and scalable. VE-Trac Dual can work in applications ranging from 80 kW to 300 kW. The first VE-Trac Dual device to be released is rated to 750 V at 800 A, which ON Semiconductor says is double the capacity of competing devices. The device is qualified under AQG-324 (European standard for power electronics) and features an embedded smart IGBT. Over the next few months, ON will release additional devices within the VE-Trac Dual platform that feature higher voltages and various current level options.

The VE-Trac Direct platform offers direct cooling for better thermal performance. The first product on this platform is housed in a six-pack configuration that will allow OEMs to achieve multi-sourcing with minimal layout changes.

Both VE-Trac Direct and VE-Trac Dual platforms are able to operate continuously at junction temperatures up to 175º C, allowing more power to be delivered within the compact footprint of the modular solution.

ON Semiconductor VP Asif Jakwani said, “These new highly integrated devices, and the VE-Trac program as a whole, demonstrate ON Semiconductor’s commitment to delivering energy-efficient innovations within the automotive space that address current challenges and help drive the rapid evolution and adoption of electric powertrains.”
