The first two devices are, according to the vendor, 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 Semi 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 Dual device 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 NVG800A75L4DSC is an AQG-324 qualified module with an embedded smart IGBT that provides a faster reaction time for the integrated over-current and over-temperature protection features and delivers a more robust overall solution. Additional devices within the VE-Trac Dual platform with higher voltages and various current level options will be released over the coming months to allow a wide range of emerging applications to be addressed.
The VE-Trac Direct platform, meanwhile, offers best-in-class performance and benefits, including direct cooling for excellent thermal performance. The first release on this 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.
Both VE-Trac Direct and VE-Trac Dual platforms are able to operate continuously at junction temperatures up to 175ºC, allowing more power to be delivered
