ON Semiconductor has released the first two devices from its new VE-Trac™ family of power modules for high voltage automotive traction inverters. These two power integrated module (PIM) devices bring electrical and thermal performance while providing scalability and automotive reliability to the rapidly growing market for traction inverters. Future devices in the VE-Trac family will include discrete power devices, isolated gate drivers and expanded module solutions, as well as wide bandgap (WBG) devices that will drive performance and expand the portfolio of products available to automotive systems designers.
The first two devices to be released are ideally suited for use in the main traction inverter of all types of electrically-powered vehicles including battery electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV) and full hybrid vehicles (HEV). With the release of these two devices, ON Semiconductor enables two traction inverter design platforms: 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 within a compact footprint for traction applications. VE-Trac Dual can be a platform solution for traction inverter applications ranging from 80kW to 300kW with minimum mechanical redesign. The first released VE-Trac Dualdevice is the NVG800A75L4DSC. The module is rated to 750V at 800A making it double the capacity of currently available competing devices. Market-leading thermal performance is achieved through the utilization of highly-effective dual-sided cooling.
The first release on VE-Trac Direct platform is the AQG-324 qualified NVH820S75L4SPB. The device is housed in a six-pack configuration that is widely recognized and adopted by automotive OEMs and systems providers; this will allow multi-sourcing to be achieved with minimal layout changes. Due to become available in multiple power classes, the VE-Trac Direct platform will allow simple and rapid scaling of power for different vehicle platforms and applications.
