Q&A: Vicor powers next-gen active suspension system
Electric vehicles evolve to support higher performance, reduced weight, and improved ride dynamics, power system design is being pushed to new limits
Case study: Powering 400V accessory loads
Supporting legacy accessories in new 800V architectures
お客様の課題
As the 800V traction battery becomes more common among EVs, loads that were powered directly from a 400V battery are now incompatible. The investment in cost and time frames to engineer 800V versions is prohibitive. Yet converting voltage for these high power loads – compressors, pumps for cooling and HVAC, etc. – needs to be as efficient and lightweight as possible to continue to maximize the driving range of EVs. The key challenges were:
- 800-400Vのディスクリートコンバータは、大きく重くコストもかかる
- 車両重量を増やさない
- 400V 負荷への電力供給のため、比較的リーズナブルに速く実装可能なソリューションが必要
Vicor ソリューション
High density power conversion using a single Vicor power module provides the solution with the smallest volume, lightest weight, and highest efficiency. Power modules are already tested, often only require passive cooling, and are easy to package virtually anywhere in the power system compartment. With this modular approach, it’s easy to adapt the solution to meet specifications for use in different vehicle platform.

1つのモジュールで出力電力37kW
最小・最軽量のソリューション
高出力 - 17kWまでなら、パッシブ冷却が可能
電力供給ネットワーク (PDN)
A single, compact NBM9280 the size of a KitKat® candy bar can power a 37kW, 400V rail to power accessories from the 800V battery. With a peak efficiency of 99.0%, the NBM is a highdensity power converter that weighs only 200g. It can be packaged for flexible placement within tight spaces in the vehicle engine compartment where a bulky, heavy discrete power supply simply would not fit.
